I just can't delete my name from the wrong category - Cast

Hi. It's a mistake of mine many years ago in 2018: I wrongfully added my name to "Cast," but I should be in the "Crew;" since I am NOT the actress, but the voice-over artist of the post production. (#181108-133527-293000)

Again, I am not performing in front of a camera, but in the booth with a microphone afterwards. The movie is called "Eternal Love" or "Haijiao youge wu dianshi" https://www.imdb.com/title/tt6772360

Later, I successfully added my name to the "Crew" - following your rules with screenshots, and was approved. (#260228-173759-064000)

More evidence for you to verify, this is the URL of the whole movie: https://youtu.be/hMAfFju0PAA?si=qArn7nNx4X_sgjQ5 Please check 1:43:13 to 1:43:23. My name is NOT on the cast credits. And please check 1:45:01 to 1:45:04. My name is credited as a voice player.

Please help me delete my name from the "Cast" - I've been trying multiple times but still get declines. (#260313-223422-485000)

I don't know how I can be more specific about this situation. If so, please let me know. Thank you.
