Incorrect "Program Type" that I can't work out how to change on IMDB

Our series is listed as a "TV Special" but it is not. It's a TV Drama Series. Because it's listed as a TV Special, the cast show up as "As Herself" "As Himself" etc. I've tried to change this, including as a last resort, by requesting that the Title be deleted so that we can re-create the entire listing. I have had no luck. Any suggestions?
