Flashcards - changing status to known

When I review the Flashcards for a given lesson, I change the status of some of them to 4. Then I go through the lesson, but these words are still in yellow, even if I refresh the page before doing the lesson. Does anyone else have this problem?

It appears that the actual status is not changing in the Vocabulary list even though it is changing on the cards. That is probably why the words are still yellow. We will fix this shortly.

Thanks Mark.
