Rhino CAD Datasmith changes mapping

I was playing with some Megascans assets which originally came as an fbx file. I placed them and modified with Grasshopper inside Rhino and then imported CAD file into UE4 scene using Datasmith CAD import. Imported geometry have different UVs than original and Rhino-edited elements. On the print screens, you can see that inside Rhino texture mapping is fine.
