Oculus Integration 1.39 Only one controller active at a time

Since the update, my biggest problem is that while I could manipulate the 2 controllers simultaneously back then, now, only one of them is tracked at a time, the tracking switch between each controller when I press any button and the other is reset at Vector3.zero local position & Quaternion.identity. I get the controller position values from

OVRInput.GetLocalControllerPosition(OVRInput.Controller.LTouch)

and

OVRInput.GetLocalControllerPosition(OVRInput.Controller.RTouch)

Of course these two lines returned the right position value back then but now only one of them return a tracked value at a time while the other one seems "disabled".
