This happened to me: A question X was asked recently and was closed as a duplicate of a question Y. I faintly remembered these questions and when X came to me as a review audit question in the close vote queue, I voted to close it as a duplicate of Y. The audit told that I had done wrong; there was nothing wrong with the question. The question was indeed ok as such, but it was a duplicate. Moreover, I chose exactly the same closing reason that was used unanimously to close the question in the first place, and I failed the audit.
I know that audits can be very silly, but this sounds like an outright bug. Could this be fixed?
Here is the audit.
