Duplicate Card Problem

Hello! I am noticing a lot of duplicate cards within the Boards and Beyond Step 1 cards, currently studying pulmonology, although have also noticed them throughout cell biology, biochemistry, immunology, hematology, and cardiology as well. I have a suspicion that I have several duplicates, but I can’t find any when I search for duplicates in the “browse” menu. Is there a way to quickly identify my duplicates and re-suspend/delete them (perhaps an add-on I don’t know about)? Also wondering if there is an ongoing project to work on the BnB cards since there are so many? Thank you all for your hard work!
