Somethings wrong

I uploaded my demo. While I was playing TF2, I wanted to see what it would be like in-game. The strange thing is I wasn't playing as Scout; I was playing as Pyro...?? When I was reloading my weapon, my game crashed! So I decided to look at the demo. THAT BLU DEMO WAS NOT IN THE GAME. Team Fortress 2 Also, what's wrong with the briefcase and stuff? Why are there multiple??
