A flaw in the words learned algorithm?
I started learning German two years ago on this website, but stopped after a while. Two years later I have come back with a renewed interest in the language, and have progressed nicely to finishing up a third checkpoint. However, upon checking the 'Words' list to check my vocabulary, I am seeing words like 'Apfel', and various conjugations of 'kennen',' as stuff I have not worked on in over two years, when I clearly have just finished a lesson with such words within them. Even doing practice sessions doesn't seem to change these words. Am I bugged? Or am I not doing something to get these changes to apply?
