On a several of our pages on the Kirby Wiki (this one in particular at the moment: Planet Earthfall) will not accept categories we add to it for some reason. Categories inherited from infoboxes on the page work, but, trying to add any others does not work. Removing the infoboxes does not allow other categories on the page, either. How can this be fixed/what is causing it?
