[BUG] XP SFX carries on through reward screens.

This was on the base version of the game so this very well could have been fixed in a patch. 
Returned from a career race and was going through the various rewards screens. I obtained the team bonus XP and this started the XP SFX noise to keep playing. The only way to get this to stop was to restart the game.
