Andrew Harrison Submission Troubles (Heirloom Audio Productions Audio Dramas)

I have started adding "the Extraordinary Adventures of G.A. Henty" audio drama series by Heirloom Audio to IMDb, and I have already run into an issue.

I made the mistake of crediting Andrew Harrison (sometimes nicknamed Andy in the credits of these audio dramas) with the profile "Andy Harrison (I)" instead of "Andrew Harrison (I)," which has already been credited in the IMDb pages for series' "promotional short films." Upon realizing my error, I have attempted to switch Andy's credit to Andrew's in the second episode, as well as to add him to the first episode with an uncredited "Show Announcer" cast role (as he also plays that role in the intro to every audio drama in the series, for it is the same intro sequence, despite him only just starting to be credited for it in the third episode), but IMDb has been denying the submissions over and over.

I have been adding the second episode's website which lists the cast, I have been using screenshots from that website and a wiki that lists both roles as Robert the Bruce and the Show Announcer in this series, but IMDb continues to reject the submissions. Can someone help me with this?
