Problem adding producer credit

Hi,

I have made several attempts to add a producer credit. The latest rejection reason is "does not meet contribution guidelines." I uploaded a call sheet to provide evidence that I am in fact a producer on the show. My editing credit was approved right away but the producer credit was rejected. Why is this happening? Would you please advise me on how I can list my producer credit? 

Here is the contribution number: #240616-151839-396000

Thank you,

David
