got my credit, lost my credit for the largest film release this year. I don't get it.

I requested my credit months ago and got it quickly. I sent a picture of the call sheet from the full day I was on the set of Killers of the Flower Moon. Months later, just before the film releases, I lost my credit for reasons of  'can't verify'? Insane. I am a Principal VO in the film (Voice-over role). My agent informed me that I would be billed as Principal Actor. For some reason.. months later, IMDB took the credit away, so I resubmitted... IMDB declined 'can't verify'. I resubmitted again with those document ids from uploading 3 images as proof... like I did originally, IMDB declined with the reason this time of 'bad formatting'. I just don't get what I have to do to get my credit back. Spent all day on set... tons of driving.. a whole day invested in this production and IMDB ignored my contribution and falsely removed my credit. I even included my phone number, agent name... all the info they probably already have in case there is an issue/question... nope. 'bad formatting' The doc ids are legit... copied and pasted from IMDB after upload. What's happening here?
