The page move of Electrick Children from AFC seems to have left categories in the article which are not visible in the edit screen. You seem to have removed one of them (2013 films) with this edit, but the other one, (English-language films), is preventing cats from being in alphabetical order. When I edited to put them in order, they appeared in order on the Preview screen, but after I clicked "Save", English-language had gone back to second place again. Do you know how to fix this?
