Adding credits

Two different questions but similiar issue.  First, I was a passenger in a vehicle that was filmed for scenes in Boston for the show Boston Blue.  It was toprovide clips making it seem as though it was taped in Boston.  I don't know if it is being used for the opening of the show or in one or a few episodes.  I have added a pay stub as proof but it keeps getting declined.  It asks for an episode but I don't know.  How do I get this approved.

Also, I was core background for a streaming ten episode show.  I did numerous shoots from May until August.  I could be in all 10 or various episodes.  I have no idea.  I did add a paystub proving I worked on the shoot but again it keeps getting denied as unverifiable.

If anyone can walk me though with the steps to do it correctly so I stop getting denied, it would be truly appreciated.  Maybe I can't do it?  I did the work so I believe I should be able to add it as a credit.  Again, any help or guidance is appreciated.

Thx in advance
