It says that it has 11 games, but I count exactly 10. (It stays off-by-one if I add or remove games from it.) Does this happen because a game was Collective Shouted, or what?
/c/4337983/maybe-play-later (I removed some NSFW games from the collection but the count is still off by one)
And IDK how to answer the second part, because the UI only shows you the count when you go to add another game to the collection...
