Why do all my enhancement requests say they are closed?

I voted for an enhancement request today, after which I was taken to a list of my existing requests where I noticed it shows the status on all of them as closed - including the one I just voted for today.

Can anyone from SW explain to me what this means?  None of these enhancement requests have been implemented to my knowledge, so does that mean they are closed and will not be implemented?  If so, I would love an explanation to some of them as to why they are not valued - a few I know had a lot of votes and there is at least one that significantly impacts my company.
