Normally, when a question has one or more votes to close, we see the number by the "close" button, as "close (3)". I've recently noticed a couple of questions which I had voted to close, that do not display the number.
For example, see this question. I don't see a number by the close button. However, if I click close, I get the message "You have already voted to close this question".
Are others seeing this behavior?
