Bookmarked Films Limit?

Hey all,
Is there a limit on how many films you can bookmark in Theater mode? I’ve bookmarked around 30 films or so, but it only shows 22. What’s going on?
If there is a limit, what happens when I reach it? Does it unbookmark the oldest films? If so, is there a way to get them back?

I am asking because I bookmarked some of my favorite matches (first win in FFA, etc.) and they are all gone. I wish there was a way I could store bookmarks on my Xbox.
