Deleted contacts not coming off of segments list

Hi, I use the segments feature to remove people from our email lists who are no longer affiliated with our organization. In doing so, I just ran a segment and deleted several people, and got the confirmation banner at the top of the page. However when I refresh the segment list, they are all still listed. If I go to the contacts list to look them up, though, they are no longer there. So they have been successfully deleted but the segments are not being refreshed. PLEASE FIX! It says right at the top of the segment screen to refresh in order to see a new list but that doesnt' actually work. I have tried in Firefox and Chrome so it is not a browser issue. It seems to be a caching issue on your server side.
