Is there a limit in playlists?

Is there a limit in individual playlists in regard to number of TV shows or episodes? This is what I have encountered. Add TV shows in a playlist:

Seinfeld
Friends

Freaks and Geeks

Then I added King of Queens, which gets added but it removes Freaks and Geeks. Then if I re-add Freaks and Geeks, it removes King of Queens. This behavior doesn’t seem to be tied to these two shows. I don’t know exactly how many shows I have in that playlist but it’s no more than 10.

This randomly resolved itself after troubleshooting another issue by removing all cache and re-installing the app.
