Delete a credit of myself

Hello all! This is getting crazy. I've written 3 times that I'm not the person credited in a shortfilm. Everytime it gets declined for lack of evidence. I don't know the team nor the production company, nothing, in order to ask them to amend this. This is a mistake. Why IMDB doesn't take my word? I can surely prove that I'm correctly credited in all the other projects (with callsheets, contracts, on screen credits, etc.). But I cannot succesfully prove that I'm mistakenly credited in this one. I don't know if the IMDB team is using AI, which worsens the detailed examination of each case. 

Thank you!!
