Player.getIsMasterClient() giving wrong result?

Hey, I have this function from LoadBalancingListener override

void PhotonLoadBalancingListener::joinRoomEventAction(int playerNr, 
	const ExitGames::Common::JVector<int>& playernrs, const ExitGames::LoadBalancing::Player& player)

and everytime I do

if (PhotonLBClient->getLocalPlayer().getIsMasterClient()),
it is always returning true for every player, even for new player joins.

I also tried taking player from the function parameter and calling
player.getIsMasterClient(), it's also returning true all the time.

Am i doing the wrong things? do I need to loop manually through all integer JVector and get the lowest one to check if it is master client?
