Layout / Border Problem

Hello there

I’ve a problem with the Layout of the borders from some blocks that can be chosen in the Visual Composer.

If you go on my Homepage http://www.blackrift.eu you can see that the News Box has the standart theme border but the video from Halo 5 doesn’t have any borders at all. What can I do to change this? Nearly all blocks that can be chosen don’t have the theme standart border.

Greetings
Ove
