The physicalsurface node is a tricky root ... it was built with certain goals in mind. Could you show us some screen shots? According to Teyon Alexander during the early release of Poser 11: "The main purpose of the Physical Surface root is to allow for compatibility with maps out of programs like Quixel Suite and Substance Designer/Painter. Can you use nodes with it? Sure but it's really more focused on supporting maps like Albedo, Metallic, Roughness, etc. without the fuss of having to fiddle with nodes." Now having quoted that ... you still should not have this issue. But we will work through this. This root node does have it's limitations.
