Sever won't let me in, because it think I still am in. And it won't let me favorite anything

At launch I got on the lowest official sever I could find (32/40) but only remembered part of the number. So after establishing a base I got off to check but it still said 40/40, I went to battlemetrics(dot)com to check and it said I was still in. I can’t refresh because it keeps “searching.” Also when I tic favorite, it will star till I leave the page it only remembers my server as a reacently played not a favorite which sucks because I can’t just change the filter to favorite.
