Credits disappeared. Could you tell me what happened and why?

That's no problem. Will do.
But all was accepted before so could you tell me what happened?

@Robky​ That unfortunately is internal information, but you should have no problem at all if on-screen evidence is provided.

Cheers!

Resubmitted with proof.
I need to know at least if it was IMDb's decision to remove the credits or someone else is trying to undermine my work.
