Manic Monday Bonus--The Queen, Demoted!!

In the early 1950s, Atlas published:

Nothing remarkable...gorgeous blonde living in Africa with her father, he is eaten by a lion, a trusted native trains her in the ways of the jungle...and she becomes Lorna The Jungle Queen.

Well, if you've read enough Golden Age jungle hero books, there's not anything particularly interesting about Lorna.

But after 5 issues, the book's title suddenly changed to:

There was no change is costume, origin story, cute jungle pet, tone, whatsoever.

For her last 21 issues, Lorna The Jungle Queen just became Lorna The Jungle Girl.

Why was she demoted from Queen to Girl?

Perhaps the was a copyright/trademark disagreement with some other "jungle queen"? Perhaps publisher Martin Goodman or editor Stan Lee had some odd whim that "Girl" would sell better than "Queen"? Was there a reason at all?

I'm sure there was some reason, but I've never been able to find it. That's your cue to tell me what you read in all your fancy book learnin', readers.

Or maybe we can just have her explain it herself when she turns up as a guest-star in the next Agents of Atlas story...
