I have a deck with many duplicate cards. The duplicate cards all have the same template， but I’m not sure where to start with this. I’m not sure this is something genanki does. I would appreciate some help. Thanks. ， so I created， the same card type and the same data (I double checked the html) in the same fields. The deck uses a custom template and it’s notes should only generate one card type.These duplicates aren’t detected by ‘Tools → Detect Duplicate’. I’m not exactly sure how this happened. I made the deck by using a custom Python script that generated a apkg file from a json file using the genanki Python module. It look awhile to fine-tune the script， then delete that deck. It would also really be a pain to do this for hundreds of cards. I can write scripts with Python， if I do that it changes the data in the fields on both the cards (possibly because they are still the same template). The only way I have figured out to delete the individual duplicate cards to move one card into another deck， because I used it for awhile before I figured out this problem. I just want to delete the duplicate cards but keep all the other cards and metadata. Something like this: If I haven’t reviewed any of the cards in note- delete all but one card If I have reviewed one of the cards in note- keep card I have reviewed and delete rest If I have reviewed several of the cards in note → keep card oldest card (first card I reviewed) and delete rest I know the recommended way to delete an individual card is to empty the fields and use the “Empty Cards” option. However， imported and deleted the deck apkg file several times. I think I forgot to delete the previous deck the last time I created the deck. I think I merged the two decks. It might been something I did when I was fixing up the deck. I don’t know why Anki suddenly doesn’t seem to mind multiple duplicate cards with the same template and card type or why they don’t register as duplicates. I don’t want to delete and recreate the deck，。
