Working my way through all the features of flashcard. Can't work out why this is happening, I know I have say 25 cards in a catergory. Starts out ok 1/25, 2/25, then it might jump to 3/23 etc. Instead of testing me for 25 it might test only 22 or 23, what is happening to the missing cards. When i have a category with 25 cards I like to be tested on 25 cards, not that interested whether a card has a 400 rating or 100 rating. Do like the feature of being able to review the cards that you got wrong
