Add credits for visual effects (Main title design/Opening sequence design)

Hello community!

I'm a main title designer, working for studios and make openings or ending credits design for film and Tv show, and only one TV show has my credits which credits "Visual effects - Main title: designer"

and have submitted other evidence including contract, screenshot of the article which has my name on it.

got rejected for "Does not meet contribution guidelines."

as I checked the guidelines, it doesn't tell me how to solve it, so could anyone help me with it, thank you very much!
