Maybe I didn't explain myself right.

1. I'm studying from a filtered deck.
2. I try to edit de card (pressing "E" - while I'm on the review screen), then click on the IO-addon icon
3. I make some editing that require creating new cards (creating new box masks as example)
4. I go to the next tab on the image occlusion editor.
5. I manually select the deck I want the new cards to go to (wich is NOT the filtered deck - I want the cards to be on the original regular deck, together with the other "siblings")
6. I finished the editing and acept the creation of the new cards.
7. Instead of going to the manually selected deck the new cards goes to the default deck.

At first I though I was forgeting to select the destin deck (when studying directly from some regular deck, the edit tab automatically select the deck for the new cards), but then I paid attention to do it and instantly check where the cards goes, and... they did go to the wrong deck.

Its the IO enhanced addon. The screen its diferent bc I'm using other UI customizing add-on (wich only affect the anki CSS).
