When exporting an armature to Unity using FBX export the transform data for Child bones is exported incorrectly.

As you can see from this image transform position data is showing some strange result - numbers followed by the letter e-(number) In reality any value ending in e-(number) is actually zero. I've tried every method possible to export to FBX and no matter what I try I still get these weird values in Unity? Myself and several other Unity uses all have the same issue with different armatures, so we think it must be somethign to do with Blender export settings? For now we are zero'uing out thsoe valules so not to confuse other colleagues.

Any hep would be greatly appreciated.
