Shaded elements and mesh lines doesn't display correctly

How to make this mesh display back to normal?

 

When I click Shaded elements and mesh lines, the meshes will become all black.

 

I've tried to reset Hypermsh setting back to default, but it didn't work.

 

Any suggestions would be really be appreciated!
