Generative fill wrong result
Here's the original photo (a free adobe stock photo):

I selected the man on the left rear including both his legs, then I typed into generative fill "a dog", I get this result:

I tried "blurred fence and trees in the background", "tiger" and both also resulted in a new person there. The only exception is to type nothing, in which case the person is deleted:

Deleting a person is very useful, but why can't it replace the person with other things?
This is done with PS 25.4.0 running on windows 11
