"Potential duplicate: Your title appears to be a duplicate of a title that is already listed on IMDb." - but it's not...
I've received the error status "Potential duplicate: Your title appears to be a duplicate of a title that is already listed on IMDb." for an episode (23.33) of Holby City that I submitted on 16 November 211116-224356-072000.
I can imagine this situation existing if two people independently submit the same episode, and one submission is being processed (but is not yet visible) when the other is submitted.
But this is not the case. Episode 23.33 is not visible on either the normal IMDB site or on the Pro site. If I try to add it again now (after receiving the error status on my original submission) I am not blocked from doing so, which tends to suggest that IMDB does not have the episode already in its database.
I can easily submit the episode again and see if it goes through this time, but I thought I'd alert the admins first in case there is a problem that is being rejected for a reason that doesn't match the error message that I'm given.
