How to change profession listing in search?

I believe that sorting is done automatically, so if you have more acting credits (as a narrator) then those will show first. There's nothing to do about that.

I doubt you'll be allowed to delete the narration credits either, especially if you're credited for it in the movies/series/documentaries in question. Otherwise it's just a question of time before someone else adds it back to the profile. The removal of correct, credited information is next to impossible.

You're not alone in this department, though. Take for instance Steven Spielberg, who's known primarily as a director, yet his directing credits are shown third on his profile. As a normal user I often find these sorting issues troublesome, and wouldn't mind if there could be implemented a manual override to show the primary profession over the most credited ones.
