This question already has an answer here:
I think there is a small loophole in review audits. It basically ignores closereason filter which I've selected.
For example when I'm selecting filter only duplicates (or any other), the audit will ignore the filter by showing non-related questions to that filter such as too broad, which obviously indicates it is audit without even looking on the question it-self. I haven't tested if the same is happening with tag filter. However I've never seen the review audit which is flagged as duplicate.
