How to remove an inaccurate credit from my profile?

I would really appreciate some help if possible. 

There is a credit on my profile which is incorrect. I did not work on this project and I would like it removed from my profile. 

I have submitted a removal request multiple times nothing has ever happened.

My profile : https://www.imdb.com/name/nm5992785/ 

The credit : https://www.imdb.com/title/tt25406638/reference/ 

Any help would be welcomed. Thanks so much.
