Yesterday when i got this card it was all fine but today i tried to learn this deck again and i discovered Anki made 5 cards with 5 cloze but i just set one cloze ??? I cant even delete the Cloze 2 to 5 because it also deletes the Cloze 1 :
I suspect that you created five different cloze deletions ( {{c1::}}, {{c2::}}, {{c3::}}, {{c4::}}, {{c5::}}) after having already added the note, and then manually changed them all to {{c1::}}?
To fix the current issue, try going to Tools > Empty Cards
To prevent this from further occurring, the next time you want to have 2+ cloze deletions with the same cloze number, you may use this button or its shortcut (Ctrl + Alt + Shift + C)
