I experienced the same issue after my wife setup the Driver Door unlock mode, only driver door is allowed to open. After you get inside of the car, you need to click the LOCK/UNLOCK icon on the screen TWICE. The first click is to LOCK all the doors, the second click is to UNLOCK all the doors. There seem to be no "Unlock All" button or icon to do that directly, on top of that I think having 4 lock/unlock icons to specify which door to control is a good idea.
