Materials not applying to datasmith model

I am new to unreal and recently brought a sketchup model into unreal through datasmith but any material other than the ones already applied to it in sketchup seem to work. Also the sphere in front of the selected floor has the same material yet only the sphere has it on just to show the materials do work.
I am sure it is some easy fix but i cannot figure it out for the life of me so any help would be greatly appreciated!
