Generative Fill the word "finger" seems to be against the guidelines

The title says it all:
In Photoshop, typing "finger" in the prompt box triggers an "against the guidelines" error.
The same prompt returns a result in Adobe Express "text to image" as well as in the Firefly website.

It was initially reported by a user who tried multiple prompts that included the word, as well as the word all by itself.
I was able to reproduce the error on my end.
