I'm a bit confused. In the manual it says that under Flashcard Testing -> Profile there should be the options of Simple, Weighted, and Space Repetition, but what I see is Default, Characters and Pinyin. Why? I started looking at the profiles when I noticed that I was being shown the same flashcards over and over again, even when I got them right. I have a deck of c. 200 cards and have it set to show me 40 per session, but rather than show me new cards from the 200 I see the same cards many times. In a given session of 40 almost all the cards are the same ones that I saw in the previous session even if I got them right. I clearly don't have the right settings enabled, but I'm not sure what is causing the problem. Any suggestions?
