Only credit being declined despite blatantly obvious evidence

I composed the title theme for a web special where a certain veteran voice actor who's union is on camera discussing his work and experience with the host for a minute fifteen seconds. His name is on screen as they introduce him AND in the end credits under the section being specified. This was filmed at an event for which he is also listed on the roster. EVERY OTHER credit went through like a breeze and did not require any extra "evidence". It was declined twice after including EVERY possible evidence including uploading a screenshot of his name in end credits, links to the moment in the video and credit where he appears. Is every credit for those with an agent getting some handling/screening by the agency? IMDb should at least respond with the real reason they declined it, because that puts even those of us paying for Pro on a merry-go-round. I have submitted a thousand plus entries and have yet to run into this. It's a "Thanks" credit to boot!
