Adding Title and Declined Evidence

Hello, I was just wondering if anyone could help. I recently completed a short which was broadcast by the BBC. I’m currently trying to add it to the IMDB, but everytime I do I get a ‘Declined due to lack of evidence’ message. The evidence I am providing is a link to the show being broadcast. I keep resubmitting with the timestamp for when the show starts, timestamps of the credits, even the pages of the actors who list it on their CV. It’s frustrating because I can’t think of any better evidence than a link to the show on a recognised channel. Is there anything else I can or should do?
