"Again" reviews not showing up

When I’m learning new cards and hit “again,” the cards are not showing up again until the following day, even though my learning interval is set to 15 minutes. When I get to the end of my deck, it will say that my next card is due for review in 10 hours. I haven’t changed anything in my Anki recently; I can’t figure out why this is happening. Below are my settings.

TIA

What’s the “New interval” option in the Advanced section set to?

I have it at 0.10. Here are the rest of my advanced settings as well:

Try setting New interval to its default setting, which is 0.

Tried it. Still having the same problem :frowning:

Not sure what’s the issue. You’ll probably get more help in the Anki forums for general Anki issues as it’s frequented by more users: https://forums.ankiweb.net
