actually, both categories are labeled as mid-level, the one called British America, French and Indian War seems redundant, since the category French and Indian War (singular) exists. The parent category is French and Indian Wars (plural) on the F&IW singular one. Which is parent of BA, F&IW one. Extra level there for no reason I can discern.
Oh, and the parent F&IW plural is not set as top level. Definitely needs some review on the order of these things.
