Sometimes it does that, just open it up and refresh it every so often. When it is 5 percent full and 1 user in queue it usually means someone is binning stuff.
If it is 6%=< full with 1=< in the queue yet no items it means you only just missed out~
Also random thing, look at this lucky bugger http://puu.sh/h3uVM/d88fa3e3fd.png It was 6 prior to refresh
