Created a new influencer but the images are all looking the same, can't change the prompts and can't delete it.

Hello,

This is my first time trying this, I uploaded a bunch of pics but there must have been some kind of error because now they look exactly like the girl of the photos I uploaded, that isn’t what I wanted, I need to change her traits and upload different pictures from different persons so it doesn’t copy an existent person… but it doesn’t let me.

Can it please be reset or deleted so I can try again?
