Section cut lines not inserting into Layout w/ rest of model

[Comfort Architecture]

A SketchUp model was created with three groups. Each group was assigned an active section cut and a floor plan scene was created. In SketchUp the plan looks great, but when the scene was inserted into Layout the section cut lines are visible for only one of the three groups. For the other two, the section cut lines are either white or not there at all. See accompanying screen shot. What's wrong here?

create a scene in skp that has the section lines not visible in the style dialog; save settings and use it as your style/scene in skp.
