I receive the following error type message from Anki when I attempt to study my cloze deletion questions…“please edit this note and add some cloze deletions”. I press the edit button and nothing appears in the edit box. I’ve used successfully used Anki almost every day for several years and I know that it is a fragile and messy system. However know I am at a loss to correct and need some suggestions this issue.
The message shows up when you are reviewing a card which has no clozes associated. You might be able to solve it by running the “Tools > Empty cards…” dialog.
