Change my Primary Video and Deleting unwanted photos

I just renew my IMDb pro subscription and I'm having a lot of trouble editing my own profile... I can't delete images in my gallery and I can't delete or replace my Primary Video. The video that is currently there wasn't chosen by me and although I uploaded two new demo reel videos, the platform still doesn't let me change it. And one of the video already have the sensitivity option on "Safe". What can I do?
