UpdateSession returns Success, but settings does not change

I'm Calling UpdateSession with changes to settings, same Keys, but different Values, Including OCULUSPOOL as a KEY(not changed).
This also includes chaning "Settings->NumPublicConnections".
This all works on SteamSubsystem, but not for OculusSubsytem.
I'm guessing it goes to 
FOnlineSessionOculus::UpdateMatchmakingRoom
-> FOnlineSessionOculus::UpdateRoomDataStore
and finally triggering 
-->TriggerOnUpdateSessionCompleteDelegates(SessionName, true);
As it is reporting a success?

But when other client do a findsessions, the KEY/VALUE settings has not changed?
