Issue with exporting OBJ with materials

Hi,

After updating Rhino 8 for Mac to the latest update I have had issues with exporting OBJ files with materials. I export both the OBJ and MTL file, but all materials are renamed as diffuse_ControlText and completely empty in both files and therefore they do not show up/exist in the OBJ-viewer.

I have not changed my export settings.

How do i fix this? Should and can I install a previous version of Rhino 8? Does anybody else have experience with this?
