Are you sure there is no Hunter pickup in the map you are playing? Try to set setting "When everyone except 1 player is dead, then:" to "start the next map" and try it again. (To test)
tried it it's still dont work fine , its only like this on DD maps , on DM maps it worked perfectly
but on DD maps its not put scores automatically and when someone wins after 1 vs 1 fight so on next map it goes to random map and not that maps i was chosen
