Anki Help
1

hi,

if i use is:new now, there are some old cards that i “recycled” thru anki 's menu and also an addon (forget what they are).

is there a easy way so i can differentiate them?

in these cards, there is still last time’s review result yet the “is:new” still select them as new cards.

i did wrong and mixed them, appreciate help.

thank you.
