About saved translation of known words

When I mark a word as known, I sometimes see the translation of the word is not correct. I assume I should correct this before marking as known, but I never do.

The same problem is with all blue words when I end the lesson. Many of these are probably saved with an incorrect translation. I’m not sure if this is a problem, because if I know the word, I also know the meaning of the word. regardless of the saved translation.

If a word is marked as known from the get-go, isn’t it stored without a definition? I see a list of suggestion when I click on such a word, but the stored definition field is empty.

@MarkSiip If you mark word as Known directly in a lesson (blue to white), definition won’t be attached to it.
