Photoshop generative fill question.

hello

I want to use the generative fill feature to erase a person and leave only the background.
When I specify an area for the person and press fill, it always puts another person as a
as a replacement. This is true even if I put a sentence to remove the person.
It doesn't just happen with certain photos, it happens no matter what photo I import.
If you have a solution, please let me know.
