Most of them haven’t been available for a while already, but you wouldn’t find out until after you’d click on them.
It’s just that the way the shows are sorted in the project contribution has changed and also it’s not possible to click on them anymore, instead it’s shown that the show is not available anymore.

Actually, since I’m making a list of shows subtitled in Dutch, this change makes it easier for me (as I used to click on so many links, just to found out they were not available).
