FBX Transform does not scale skeletal mesh with multiple pieces properly using the Import Uniform Scale option

Importing a skeletal mesh fbx from blender and setting the Import Uniform Scale option for the mesh to a higher value, like 100, results in only one of the meshes being scaled while the other is left at it's original scale.

Notes:

• Happens with the users FBX from Blender, but if I open the FBX in 3DS Max and export it, there is no issue.
• If left at the original scale of 1.0 box import with their correct scale.

Blender source file and Exported FBX have been attached.

1. Import attached FBX file
2. In the Import Options set the Import Uniform Scale to 100

Regression: no

Results: Both meshes are combined for the skeletal mesh, but they are not both scaled. Only the top box is scaled properly. The bottom box is left with its the original scale.

Expected: Both should be scaled.
