Material on site plan top comes in metallic and upside down. Need help asap

The materials on my topo come in upside-down. The top side is dark and has a metallic think. The underside looks correct. The rest of the medal works as it should. This is the first time I have encountered this issue with a topo - my methods and settings have not changed. I am exporting Datasmith from Vectorworks 2022 into TM 2023.2.1. I am including screenshots showing the top and underside of the model where you can see the materials mapping correctly on the underside of the topo. I have tried the following:

-Rebuilding the entire topo in a separate file and importing.

-changing the materials on the model before exporting Datasmith

-Making the material 2-sided

-Importing into a separate TM file.

I am wasting a significant amount of time trying to fix this with no solution. Any pointers would be helpful
