Smart Materials containing Paths and Warp Projections scale change when adding new Texture Sets

Our team is running into a problem in which if we create Smart Materials that contains Paths and/or Warp Projections  and apply that Smart Material to the same Texture Set, but have subsequently added a new Texture Set to the fbx prior to applying the Smart Material, the existing Paths/Warp Projections within the Smart Material are scaled incorrectly in relation to the updated geometry. For example the paths look like they're scaled up 10 times the original size.

Steps:

1. Texture_Set_A containing paths or warp projections, create a Smart Material.  

2. Import a new fbx with the original Texture_Set_A, but add a Texture_Set_B to the project. 

3. Apply the smart material made from the previous Texture_Set_A containing paths/warp projections to the updated Texture_Set_A (which now also includes the Texture_Set_B addition).

4. Results in paths/warp projections no longer matching the scale or world space position of the original Texture_Set_A

I have double and triple checked the world space transforms of the geometry as well as reimported and exported geo multiple times to and from Subtance Painter and Maya, but get the same results. I've also tried creating multiple Smart Materials applying them to various Texture Set configurations and still get the same issue.

Any help would be greatly appreciated.

Thanks,

Erik
