Wont accept my credit

Hi there, I served as a co-executive producer on a series that is on television right now, although I was not credited on IMDb. So I did go through the proper steps. I uploaded an image of my main on entitled credit to the form. Today I received an email saying that it was rejected. That I have to refer to the submission guidelines. However, I have no idea what guideline they're talking about. I cannot email them back. There's no support area. This is the only place that I was told I can get some information. Can anybody please offer some direction. Thank you.
