Missing object and detail when importing to twin motion 2020 version 2020.1 (6.0.2020.1)

Hi, after I tried to export my sketchup to twinmotion, the object is missing, does anyone have the solution regarding this matter. Really Appreciate your help

the spec is
mac os catalina
radeon pro 550xt
skp 20.2.171

I dont think it is possible because the part is missing.

If sharing the SKP isn’t possible, can you post the same view image while you have Face Style set to Monochrome?
