Their complaint came before those edits.

What seems to have happened is that they noticed a (probably empty before then) category that was created by the software when the wiki was made. They didn't know what it was doing there, so they asked here. Before my first reply, they had already made the edits you describe, fixing the problem by incorporating both the previously-used and the software-created category into the hierarchy.

TL;DR: They noticed something and then solved the issue themselves before anyone could respond. But they aren't complaining about themselves, because the category was there before the edit, as an empty but created category page; see http://crystalprism.wikia.com/wiki/Category:Content?oldid=3655
