I started having problems with my anki (Mac version) displaying cloze fields on my cloze deletion cards (“no cloze deletion” message) and in trying to fix the error I must have messed up the coding/template for cloze cards because now when I select the cloze card type there is no option to add a cloze field. This is what I see when I go to the template for the cards (despite having chosen Cloze at the note type when making the card:
That note type might be called Cloze, but it’s not that. At a glance, you can see that it has multiple card types, and that wouldn’t be one of the field names if you were using the default type.
