Weird thing colour has changed from white to black

I'm playing a game with white and my opponent resigned. Now the same game is still there but my opponent's name has changed and the colours are reversed. Now it's my turn, but this position was given up earlier. Also it says : this game has no move history.

It is customary in help situations to quote a game number so others can look and try and answer your question.
What I will say is that it is extremely rare for the system to be at fault.
You could send feedback(the option is at the bottom of every page )but you would still need to quote a game id
