Generally when there are one or more votes to close a question, the number of votes are shown like this
close (1)
For a specific question that I voted to close, I happened to notice that there is no vote count (there should be at least 1 vote, mine).
When I click "close", the close question dialog informs me that I have already voted to close the question. I do see close (n) for other questions that have a vote or more to close.
Bug?
