Zanki categories are not the same

🐛 Bug

Before the error happened, I was…
[Replace this text.]

this happened a while back, when I got v12 anki, all the cards got tagged to the anking deck instead of the subdeck it was meant to be in.For example my cardio step 1 cards arent in its own section but its in the main anking deck so there is no chance I can isolate them and review them without doing all my cards that I unsuspended unless I change them manually. is there a way I can revert my cards to go back in its original subdeck without ruining my intervals or anything with my deck.

Hello, :slight_smile:

There isn’t a way to automatically revert your subdeck organization aside from restoring from a backup, which would affect your learning progress.

Because the Zanki and AnKing cards share a lineage, they will necessary overwrite each other due to the way that the Anki software works. But, you can organize your collection into subdecks per your preferences which is what most folks end up doing

This tutorial can walk you through an example of what that basic workflow might look like: How to Create Subdecks

Please let me know if that answers your question, and if there’s anything else I can help with. :slight_smile:
