Combine MCAT deck with previously used MileDown deck

I was wondering if someone could help me out with Anking MCAT deck. I’m currently doing my re-take of the MCAT, but used the MD deck where I also added my own cards for my first take. I would like to use the Anking deck for my second take and was wondering if there was any way to integrate the two decks? I reviewed the “protect my scheduling” section of the Anking MCAT overhaul V2 and added the special fields add on, but the decks are still separate in my Anki. Is there a way to merge them together so repeated cards are removed and it becomes one deck?

Also, I’m also confused with the number of notes that are showing up in the Anking deck. Under the tags section it shows the deck to have 2885 notes, however under decks it shows 11 notes. Just wanted to see if anyone could help me out with what I might have done wrong when downloading the deck.

There is no way to merge two different decks and remove duplicates as of right now.

Also, the special fields addon is no longer being used so you can only protect fields using right click → ankihub protect or manage protected fields on AnkiHub

If there is a different amount of cards, try this:

Please try resetting your local changes. To do this:

Go to browse in your Anki → at the top click on ankihub addon tab → press reset all local changes

This will restore everything to what AnkiHub has unless you have specifically protected those fields

Thank you for the response Ahmed, on reddit I got a response saying that maybe the decks can be merged? Would you be able to clarifying the screenshot below?
