Delete a credit

I just submitted a new title and credits for a film I produced. All looks good except I am listed as the "Star" of the title, whereas there should only be a single narrator listed at this point. How can I delete that credit without interfering with my producer credit. By the way, on my own page, I am not listed as a cast member of the new title. When I entered the title I added my own name under "self", but did not think that was in any way connected to one credit or another.
