Cloze- 8e7f9 problem

My boards deck has over 1500 Cloze-8e7f9 that do not work! They are cards that have multiple close questions and one answer. I have not been able to find anything about these cards online, does anyone know how to get these to work?



Click the Cards… button, then edit the note type to add all the other cloze fields, eg {{cloze:Q2}}, {{cloze:Q3}} and so on.
