Vocabulary by lesson doesn't get all words from the lesson

When I try to review flashcards by lessons (from the Vocab section on my Android tablet) it won’t show me all of the words. I have amount of cards set to 200 but it seems to only bring up a hand full of cards to review. It won’t let me study all ‘1’ and ‘2’ level words from that lesson for example.

Are you saying that words do not show in the list at all, or when you start the review they aren’t included?

When I start the review only some are included.

Thanks, we will look into it.
