Hi. You added a couple of categories - Aliens, Locations - to characters/places that didn't have them. Note, however, that those are so-called supercategories. If a page is already categorized in one of the supercategory's subcategories (in this case, The Reach and Headquarters), there's no need to add the higher category.
