Bug from Retargeting a Base Pose

[Peude]

Hi,

1. New1.jpg - is new import FBX.
2. Bone1.jpg - after i press View Pose and adjust left shoulder bone.
3. Bone2.jpg - after i press Save Pose the bones return from default location.
   Note: But when i tried to press again View Pose the shoulder are adjust from before i press Save Pose. And not the original/Default position.
4. New2.jpg - sample preview with same T-Pose.
5. New3.jpg - Shoulder same bugs.

Please check the View Pose, Hide Pose and Save Pose. There are error from View Pose and Hide Pose with different data save.

Use: UE4.5, UE4.5.1 to UE4.6 Preview
FBX/Obj Files

Thanks.
