So I thought something might be up with my cards… sometimes I thought I may have been encountering “new cards” that I know I have seen/reviewed before on at least one of my devices (laptop, iPhone or iPad) or seeing a card card twice on the same day(that I know had a longer review interval than >1 day).
I was finally able to catch the latter issue in the act (see attached screen shots).
I have no clue how to fix this and it is becoming kind of frustrating! I’ve tried deleting decks (de-linking on Ankihub) and re-adding. Re-installing Anki (and add-ons). Has anybody else had this problem? Any recommendations for how to fix this issue? Thanks in advance!
I reviewed the following card at 8:03a today and then got the same card again just a few minutes ago (there is only one Cloze for this card, so that wasn’t the issue).

Thanks for all the detail and the screenshots—those are really helpful.
A few things can cause “already‑answered” cards to re‑appear, even on the same day:
1. Multiple devices not fully in sync
If you review on multiple devices (laptop + iPhone + iPad), and one device is out of sync, Anki can “replay” cards you already did on another device.
Steps to check:
On every device:
Sync.
Make sure there are no sync conflicts or error messages.
On your main device (usually your computer):
Tools → Preferences → Network and make sure you’re syncing only to AnkiWeb (not any third‑party service).
After doing a full sync on one device, do a one‑way sync (“Download from AnkiWeb”) on the others to ensure they’re all identical.
If the problem mostly happens right after switching devices, this is the most likely cause.
2. Custom study / filtered decks
If you’ve ever used:
Custom Study (e.g. “increase today’s new/review cards”, “preview new cards”) or
those can legitimately pull already‑seen cards back into today’s queue.
On the card’s Info screen, look at the “Deck” field and any log entries saying “moved to filtered deck” / “returned from filtered deck”.
If you’re unsure:
Delete any filtered decks.
Avoid Custom Study for a day or two and see if the issue stops.
3. Card duplicates vs. one card
You mentioned there’s only one cloze, which is good to rule out extra card types. Still worth checking:
In the Browser, search for the card’s Note ID (from the Info window).
Confirm there is only one card attached to that note.
Also search by a unique part of the text to make sure there isn’t a near‑duplicate note that looks the same.
4. Scheduling options / daily limits
Sometimes a card looks like it repeated “today” because:
It was due just before midnight and again after midnight, or
You changed settings (e.g. maximum reviews/day, “bury related new/review cards”) and the queue got reshuffled.
From your screenshot, the intervals (7 days → 12 days, etc.) look normal—so this is less likely, but if you notice cards with 1‑day intervals unexpectedly, check:
Deck Options → Reviews
Make sure “Maximum reviews/day” is not extremely low.
Confirm “Day starts at” matches your actual study times (e.g. 4:00 if you often study after midnight).
5. Interaction with AnkiHub
AnkiHub itself doesn’t normally change your scheduling; it only updates note content and tags. That said, to be safe:
In the Browser, find the card and look at the “AnkiHub” columns (e.g. AnkiHub Note ID).
Confirm it’s properly linked, not duplicated as a new note.
Make sure you’re not:
Deleting then re‑subscribing to the same deck frequently (this could create duplicate notes that look identical).
Importing .apkg versions of AnKing in addition to using AnkiHub (that’s a common way to end up with doubles).
What I’d suggest next
To narrow it down, could you:
Post one more screenshot:
The full Card Info window for that card, including the bottom history table (you already partly did this—just ensure date/time entries are clear).
In Anki’s Browser, search for that card:
card:123456789 (using its Card ID from Info)
Confirm there is exactly one note and one card.
Let us know:
Which device you were on at 8:03 am vs. when you saw the card again.
Whether you used Custom Study or any filtered deck on that day.
With that info, we can usually tell whether it’s a sync / multiple‑device issue, a duplicate card, or something related to filtered decks.

Thanks for the extra details and the full Card Info screenshot—that helps a lot.
From what you’ve shown:
Same Card ID
Two reviews on the same calendar day
Different devices (iPad at 8:03, computer at 10:25)
Only one card in the Browser
That pattern almost always points to a sync timing issue between devices, not a scheduling bug or AnkiHub.
What’s most likely happening
You reviewed the card at 8:03 on your iPad.
That review didn’t reach AnkiWeb before you opened Anki on your computer.
Your computer downloaded an older state (where that card was still due today), so Anki gave it to you again at 10:25.
Now the history shows two reviews on the same day, because each device thought it was legitimately due.
How to prevent this going forward
On each device (iPad, iPhone, computer):
Before studying
Open Anki / AnkiMobile.
Immediately sync first.
Wait for sync to fully finish (no spinner / progress bar).
After finishing your session
Sync again before closing the app or switching devices.
For a one‑time “clean slate”:
On the device you consider authoritative (usually your computer):
Sync.
Go to another device → when prompted, choose “Download from AnkiWeb” (so it exactly matches AnkiWeb).
Repeat for the third device.
This ensures all three are identical and prevents partial / out‑of‑date states.
About AnkiHub in this context
AnkiHub is only updating the note content and tags, not the scheduling. What you’re seeing should not be caused by AnkiHub, and your screenshot/history look consistent with normal Anki behavior under imperfect syncing.
If you still see cards repeating on the same device without switching devices, that would be more concerning—if that happens, could you grab another Card Info screenshot showing two same‑day reviews on that one device and share it?
I had literally just completed a sync on each of my devices before I started either review (at 8a or 10a). I had also done a 1-way sync on my computer before the 10a review (on my laptop). This issue is also happening for reviews that are on the same device (I just don’t have a particular example).
I am not currently using any filtered decks (I did create one to capture the screenshots you asked for, but deleted it right after I capture the images).
Here is a screenshot from my main screen (happy to expand my EKG deck, but it’s multiple sub-decks and takes up more than the screen):
Here are two of the cards (the ones that I have posted about this). I took these screenshots using a filtered deck to search for the two CIDs (let me know if you need some other way, I just couldn’t think of one, and I will get it to you):
If you are using filtered decks, that can be a cause of cards coming up for review sooner than they are scheduled. It depends a bit on what string/s you use to create your filtered deck, but just as a reference point if you are using them that can be a reason for cards to come up for review unexpectedly early.
If that’s not the case, and you’re not using custom-filtered decks at all, we can eliminate that from consideration though.
From there, do you know if both your AnKing, and AnKing:Review decks are on the same preset? And, either way, can you share a screenshot of the deck settings for those two?
Unfortunately, if you have add-ons installed that have the capacity to reschedule cards I’m afraid it can be a lot harder to get to the bottom of things. Many add-ons are written by third parties and have functionalities and weird conflicts that are well beyond what I’m likely to be able to be familiar with
That should also add that potentially having more than one, or multiple, source of rescheduling, can also wreak havoc in multiple ways. Since AnkiHub doesn’t really affect scheduling in any way, if you’re using add-ons or other functionalities that may be well outside of my expertise, I’m sorry to say
Just so I’m on the same page: is that to say that the second review on 04-01 here was from a custom-filtered deck? Want to make sure I’m not getting turned around here
Sorry if I miscommunicated. I do use a sub-deck within the Anking deck, where I manually move cards, based on a given tag, into the sub-deck (this is not a “Filtered Deck” per using a given query). Does this make sense? These (and all of my decks) use the same presets (screenshots attached below):
Regarding Add-Ons, I am 100% okay with removing any Add-Ons that may be contributing to this issue. In a post above, I included all of my current add-on in a screen out, are there any here you recommend I delete to see if that can resolve this issue?
Gotcha, yeah subdecks should be fine. Custom-filtered decks are a bit different, but if you’re not using them then it’s not likely to be a source issue here so I think we can safely ignore that
To be honest, I’m sorry to say that I’m a bit stumped. I’ve seen a lot of things, over the years, and this is not something I recall having come across in recent memory, at least
I see that the card came up for review this morning at 8:01, you hit ‘good’, and it had an interval of 13 days. Which, obviously, means it should show up again on 04/14 or thereabouts. I can’t think of any good reason/s why it would then come back up for review 2.5 hours later
Short of an add-on conflict, or filtered-decks, or some other voodoo I’m sorry to say I really don’t know. The only things I can think of are some add-on issue
There are a couple of things that stand out to me in your user settings, mostly the absence of learning steps and re-learning steps, but neither should be impacting a review card in either case (only new cards and lapses, neither of which apply to this card). But the rest of your settings look normal to my eyes, and I can’t see anything that would explain this behavior
Of your add-ons, the FSRS Helper add-on is the likeliest to be causing some issue. But, I also use that add-on and have never had any problems with it, so I can’t be sure. From there, the ‘Special Fields’ add-on has no scheduling functionality at all, though it is quite outdated and no longer recommended for use, and it is known to have a number of oddball conflict issues with random functionalities. I have no reason to think it should be affecting your scheduling, but I also can’t think of any reason to have the add-on anymore (it used to be used alongside AnkiHub, but is now defunct and no longer necessary)
I’m sorry to say whatever it is may be out of my depth. At the very least, it doesn’t appear to be AnkiHub-related. My best guess is a scheduling conflict of some kind, though I’m just hazarding a guess there
That’s about the most expert advice you can find, there, and likelier than not they’ll be in the best position to tease apart what may be going on under the hood. A lot of developers hang out there, as well as add-on authors, and you’re not likely to find more expert advice anywhere than there
Sadly, I am not a developer myself and my expertise doesn’t really extend to all the nuances of various third-party add-ons. I can’t see anything in the screenshots you’e shared that would seem to indicate why those cards are behaving that way, and as much as it bugs me to admit I’m not sure I have any answers, sadly. Maybe it’s something terribly obvious, but nothing is standing out to me
Thanks so much for the suggestions here and for your time spent looking at this issue! I am going to go ahead and delete the ‘Special Fields"‘ add-on and then post this on the ankiweb forums.
If I am able to get some clarity, I will follow-up here so if there is anyone else with something similar, they can have a solution!
Absolutely, please do follow up if you happen to find it. At least that way if we run into it again maybe we can get to the bottom of it a bit faster
Although I hope sincerely that it’s not a common error, as I imagine this has to be a bit frustrating and I’m sorry again that we weren’t able to sleuth our way to a better answer for you. If there is anything else we can help with, in the meantime or in the future, please always feel free to reach out anytime
My powers may be limited, but always happy to be of help as best I can
Got some great clarity from someone who was able to check out this and my AnkiWeb forums post! The person who replied was able to put together a few screenshots I posted to clearly demonstrate how they could identify that there was more than likely a sync conflict, leading to the repeated card. I will make sure to keep the App closed on all of my devices except the one I am actively using for review and hopefully it will prevent this from occurring again?!
Ahh, so glad you got it figured out. And thank you for following up here, so we have this info for future reference
Danika_Dakika on the other forum is an ice, and about the best help you could hope to find. Very glad it sounds like you’re all squared away (and for sure I have run into sync issues across devices in the past as well, and the frustration that comes with it)
Best of luck in your studies, and please feel free to reach out anytime. Always happy to help anytime we can.
