My first credit that is uncredited. I noticed other actors from the show have a credit posted as their first uncredited role.

I had a uncredited role on a tv show and it says that the credit was added on the contributor page. It says under the summary box, the name of the show/episode and Cast -1 credit added. However when I go the episode page, my credit wasn't posted. This would be my first credit and was uncredited. I noticed a few other actors that were added to the cast page with that being their first uncredited role on their account as well. I was just wondering what else I need to do to have this item posted. Any help will be much appreciated, thank you.
