thanks, meanwhile I found out that all cards where I deleted "y" in the field "Add reverse direction" gave empty cards. l put everywhere "y" again but would prefer to have only one direction. I have two fields on the front side:
1) subject 2) Question
on the back side I have always three fields
1) answer 2) "add reverse" 3) comment.
Comment is mostly empty - and "add reverse" would be empty also - but in no case there is no filled field present. There is always one field with text present. Nevertheless, Cards are considered empty. What can I do?
Is it possible to change the type of card for the whole desk?
