Switching VR Camera's = double initial Rotation value

I have a strange problem when I try and swap OVRCamera's in Unity. I'm currently using Unity 5.4.1f1 and the latest ovr_unity_utilities_1.8.0.

I have edited the MultiCam script from the OculusSampleFrameworkProject_1.5.0 to allow me to swap between OVRPlayerControllers instead of OVRCameraRigs. It's set up to swap on a button press from the controller (for testing) and when the player collides with a trigger object, or when a player presses a button (using Gaze Pointer).

Anyway the issue I have is that whenever I switch to my second OVRPlayerController the initial rotation of the X and Z axis seem to be doubled so to the user the world is tilted.

For example if I leave my Oculus headset on the desk and look at the CenterEyeAnchor rotation settings for the first OVRPlayerController it may show X=-6 y=0 z=-0.1 wheras when I switch to the second OVRPlayerController the figures are x=-12 y=0 z=-0.2

I can't see why this would be the case?

The script is below.

Code (CSharp):

1.  using UnityEngine;
2. public class MultiCameraSetup : MonoBehaviour {
3.      public OVRPlayerController[] playerControllers = new OVRPlayerController[0];
4.      public Transform[] rayTransformControllers = new Transform[0];
5.      public int                currentController = 0;
6.      public OVRInput.RawButton forwardButton = OVRInput.RawButton.Y;
7.      public OVRInput.RawButton backwardButton = OVRInput.RawButton.X;
8.      public static bool doIStart = false;
9.      void Start() {
10.          UpdateCameraControllers();
11.          UpdateRayTransformControllers ();
12.      }
13.      public static void SwapBool() {
14.          if (doIStart == false) {
15.              doIStart = true;
16.              Debug.Log ("Bool Switched");
17.          }
18.      }
19.      void UpdateCameraControllers() {
20.          for (int i = 0; i < playerControllers.Length; i++) {
21.              if (playerControllers [i] == null) {
22.                  continue;
23.              }
24.              playerControllers [i].gameObject.SetActive (i == currentController);
25.              OVRManager.display.RecenterPose();
26.          }
27.      }
28.      void UpdateRayTransformControllers() {
29.              for ( int i = 0; i < rayTransformControllers.Length; i++ ) {
30.                  if ( rayTransformControllers[i] == null ) {
31.                      continue;
32.                  }
33.              RayTransforms.mainRayTransform = rayTransformControllers [i];
34.              }
35.          OVRGazePointer.instance.Awake();
36.      }
37.      void Update() {
38.        
39.          if (doIStart == true){
40.              doIStart = false;
41.              Debug.Log("Glowring Activated");
42.              SwapCameras ();
43.          }
44.          if ( OVRInput.GetDown(forwardButton)) {
45.              if ( ++currentController == playerControllers.Length ) {
46.                  currentController = 0;
47.              }
48.              UpdateCameraControllers();
49.              UpdateRayTransformControllers ();
50.          } else if ( OVRInput.GetDown(backwardButton)) {
51.              if ( --currentController < 0 ) {
52.                  currentController = playerControllers.Length - 1;
53.              }
54.              UpdateCameraControllers();
55.              UpdateRayTransformControllers ();
56.          }
57.      }
58.      void SwapCameras ()
59.      {
60.          if ( ++currentController == playerControllers.Length ) {
61.              currentController = 0;
62.          }
63.          UpdateCameraControllers();
64.          UpdateRayTransformControllers ();
65.      }
66. }
