Known words from vocab are not calculating my total

When I am reading Spanish content , if I come across a word I know and select the checkmark it adds that’s word to my total known words that is in parentheses next to my language. If I save a word and then review it in my vocab list when I know it hit the checkmark it doesn’t not get added to my total words known

A word becomes known when it moves from status 3 to status 4. The green check only means it will no longer be added to your Daily LingQs. So, if your word was status 4 already and you checkmark it, it won’t increase the Known words count.
