Viewport - Shade Objects problem

I have created a display option for drawing setup based on the pen display.

I have a problem where if I turn on “shade objects” meshes become colorized.Works great for all other objects, but some meshes will not display without colors when this option is on. Anyone know of a solution to this problem?

With shading on.

With shading off. How I want it, but would prefer to also keep the shading of course.
