Destructible meshes not visible in viewport

I have a Blueprint class containing a static mesh and four destructible meshes. When I click play in the viewport the destructible meshes become invisible, sometimes depending the distance of the player from them, but always when I overlap one of the destructible meshes and add damage, it becomes visible and destroys, can someone help me in order to fix it?

Is this a bug or something I am doing wrong?

NOTE: I make sure that they were visible in game in their settings.

I fix it! The solution was in the details panel of AddChildComponent node I just set the Mobility to Static, so If someone is having the same issue that is the solution :wink:
Hope it help others
