I'm getting the same words over and over
Whenever I click "Practice all skills" I just keep getting the same words over and over. Just now I went through and did the "Practice all skills" about five times or so and it was the same words and phrases every time! At the end it even tells you what words were strengthened, and those were the same nine words each time (nachdem, falls, wohin, kalt, vier, nein, ein, ist, ich). Let me tell you, I know these words really well now but I want to learn practice other words. This must be a problem with the software. According to my vocabulary list, I have now encountered "Nachdem" 76 times! I have the same problem if I go to the vocabulary tab and choose "Practice weakest words" Just those same 9 words over and over. Please help!
