Film being listed under "Self" for all actors

This film (https://www.imdb.com/title/tt31688606) seems to be categorized in a way that causes it to appear under the "Self" category for all the actors involved. Other threads asking about this same problem were resolved because the title was incorrectly listed as a documentary or as reality TV, so my best guess is that the problem with this one is that it's showing up as a "TV special" -- it did originally air on TV, but it's a feature-length, fully fictional film. I can't seem to find a way to change it from TV Special to TV Movie, however. Can anyone confirm if that's the problem, and if so, how to fix it?
