Problem with I know them all

I have problem with doing lings. First, I create lings. After going to the next lesson I click I know them all. Howewer rest of unknown words isn’t changed into known words. Could you help me please? Thanks in advance.

Hi Makacenko,

I just tried this and didn’t have any problems. What lesson did you try this in? Also, is it a problem with all lessons for you?
