Primitive Foliage Unbuilt Light Interactions

After building the lighting I get improper rendering of the mushrooms in the world. When I launch in PIE there is a warning that there are 22 unbuilt objects. I tried setting the world light sources to movable but then all the foliage and and trees have no shadows. What settings do I need to correct unbuilt lighting for my foliage?
