Incorrect and overlapping credits for Trevor Powers

I had attempted to delete an incorrect credit at https://www.imdb.com/title/tt2320292/ but was repeatedly denied, my last being #250110-232942-061000. Because it is not possible to receive specific feedback beyond vague prompts like "Unable to verify", I cannot know what part of my submission is wrong. I believe I already provided enough information to verify. Here was my submission: The credit for Trevor Powers is already correctly added here with the page https://www.imdb.com/name/nm9938362/. The actor can be seen in the trailer for 9:11am here: https://www.youtube.com/watch?v=7YKkjT3i5mc (at 0:50 and 1:43). Here is his Backstage profile which includes his headshots and includes his credit on this exact film https://www.backstage.com/u/trevor-powers/. I am deleting this credit because https://www.imdb.com/name/nm4047486/ is for the musician Trevor Powers aka Youth Lagoon. As you can see here, https://www.instagram.com/trevorpowers/, that is a completely different person. The same issue exists for the same actor at https://www.imdb.com/title/tt1715717/, where the correct Trevor Powers page is already credited. My deletion submission for that credit was also declined. The Trevor Powers page also has a credit for a composer on a British director’s obscure graduate film for Bournemouth University from back in 2012 (https://www.imdb.com/title/tt2393320/). I can find no evidence this composer is the American Trevor Powers aka Youth Lagoon, which presumably would have been publicized at the time given he was at the height of his career. It is thus highly likely that is a different Trevor Powers and we should err on the side of caution and move that credit to a new page.
