Why won't IMDb remove the History genre from these titles?

IMDb's definition of the History genre says the "[p]rimary focus . . . featur[es] real-life characters" and that "[w]hile some characters, incidents, and dialog may be fictional, these should be relatively minor points used primarily to bridge gaps in the record."

Except as indicated below, all of the following titles focus on fictional characters as their lead characters. Therefore, none of these titles are eligible for the History genre. Yet IMDb will not delete the History genre from these titles. Why not?
