I need to delete projects I didn't participate in from my page

I am trying to delete a bunch of credits from my page for projects I never participated in and hadn't even heard of. Once I submitted the requests, 7 are pending, but one was denied. I never did the project. I want what's listed on my page to be honest information. I don't even know how all of this got added without my approval. How do I get this project deleted? I don't have any evidence other than that I have no knowledge or history of these projects and never auditioned for them.
