Shading problem

Why, when I take a shaded Rhino 6 file and import it into Rhino WIP,
it shows the original edges in the appropriate color but will not display
the surfaces in the correct color. *see the attached file below)

Without the original file, or a screenshot of the expected result it is hard to tell whether the below is what you want or not… Since you posted a Rhino WIP file this is what it looks like opened in WIP.
