Texture mapping - odd behavior in Rhino 6

Hi all. Recently upgraded to Rhino 6. I am working on a large building project using millimeters as the base unit.

Unfortunately, texture mapping does not seem to be working the same as in previous versions. When I do a box mapping, I am unable to map more than one entity at a time and I am unable to rotate the textures along any axis. To get a decent reading of the materials, values for “XYZ Size” must be infinitesimally small; i.e .005 for each. We are not able to make the size smaller than .001.

Any thoughts? Wondering if this is a setting in options or if it has to do with the units. Same workflow in previous versions using box mapping works fine.
