There is a small bug in how the FBX importer computes the rotation matrix for nodes. It applies the "RotationOrder" property to the local, pre, and post rotation values. However, the pre/post rotation values should always use a fixed XYZ order. The "RotationOrder" property should only apply to the local rotation value. I've attached the updated file with the fix.
