Randomize start position may not be working correctly

Playing single player if I set it to randomized start it stays on that setting no matter what map I select but it only seems to actually randomize if I click it right before I start a map.  So for example, I set it to randomize start and then play a map, finish and close the game.  I launch the game later and it still is set to randomize, I select a different map and play it and it does not randomize.  I can verify this by restarting the same map repeatedly and always getting the same (default player 1) start position.  But if I click randomize again, even though it is already supposedly set, it will randomize when I start the map again.
