This may be related to my question A review audit tells you there's 5 close votes already.
I just failed an audit in the First Posts review queue. The question clearly stated that it was closed (Possible Duplicate link and everything) so I clicked No Action Needed. As the closed link was at the top of the question this seemed to be a reasonable course of action (more fool me).
I don't have a pre-audit screenshot as I wasn't expecting to need one. It basically looked exactly the same as the below apart from the score, which was displayed as 0.
