Trying to drop inaccurate History genre without success

I've been trying to remove the History genre from The Great Escape (1963), without success; although it's based on a true event (the keyword 'based-on-true-story' is present), too much has been fictionalized to meet the genre guideline - none of the character names are authentic, as they are mostly composites of different POWs or entirely created characters, and there are also a variety of other changes from the real events. This has all been well documented over the years in various sources, and the title didn't have the History genre listed for many years, likely for these reasons, but my repeated attempts to remove it again have been declined:

240314-205016-972000

240315-202519-114000

Any staff help would be appreciated.

P.S. Now that I look a little wider, I note the large number of titles with the History genre that have only a passing resemblance to actual events, all the way down to pure legend with King Arthur (2004). This, of course, was one of the concerns when the History genre was approved years ago; period films are not necessarily History, even when they're inspired by true events.
