Some Mesh not render in editor but normal in game

Hello guys.
Here are two pictures of the problem that i face, i have no idea why it happen so don’t know how to fix it.
The visible and actor hidden in game check box of the problem mesh isn’t check , just like the other normal meshes.
Any idea about this? Thanks for any advice or discussion.

I notice that something wrong in my problem description.The visible check box is check,while the actor hidden in game check box isn’t check.

well, it would be good to see a screenshot of the world outliner that contains all the objects in the scene, also maybe the objects are contained in a saparate map that’s loaded with level streaming?
