Assistance correcting credits on a film

I made a submission for two corrections to the credits on All The Sins Of Sodom.

Submission ID: #260723-055843-700000

Sue Akers plays the character of "Joyce" in the movie, but the IMDB credits list her as "Literary Agent".

Marianne Prevost does not appear in the movie at all, but is listed as playing "Joyce".

Marianne Prevost appears in another Joe Sarno dirtected movie around the same time, but looks completely different and is not in this movie at all. There are no on screen credits for actors, only technical credits. But the director himself Joe Sarno confirms it is Sue Akers playing Joyce in the commentary he did on the DVD release. I'm unsure what evidence to provide as there isn't an image, it's a audio commentary track. The specific release is the 2017 Film Movement DVD.

Is it possible to get the above corrected? If not removing Marianne Prevost (who is not in the movie) at least move the character name "Joyce" to the correct actress Sue Akers, and just leave Marianne there with no character name.
