My influencer is weird

Hey. I created an influencer but i don’t like her collarbone. when i try creating images by my promt it doesn’t change her collarbone. Same with her smile, even if i type in the the prompt she doesn’t smile at all. I would like to delete her and make a completely new one from different base image. But i’m getting error. Can you delete her/reset it somehow for me please so i can create a new influencer?
