Human Ears: Bane of My Existence

Greetings.

I make characters that look a lot like this for my roleplaying campaigns. I run into major issues as it almost always want to generate Kitsune with human ears, even though I have set parameters for "No human ears in this project" and ChatGTP will tell me back and forward that it knows this, but will continue to put human ears on the characters.
I have educated the machine that "these characters don't have human ears" and "animal ears only" but without avail.

I'm looking for advice - how do I get it to stop adding human ears?

P.S. Even if I can get one good image, it will add them as soon as I look away.
And yes, that's an American Gothic spoof.
