Fullwidth Section with Columns like the demo

I’m not sure if I’m guessing right, in that the theme demo has a Fullwidth Section that has columns?

Please see attachment.

I’m trying to duplicate this in where I can have columns of shortcode items across.
But in this case with “Icon Box” shortcodes. It just stacks them. Not sure what I’m doing wrong.

I also went into the Row settings to break up the columns there, but when I do that, it breaks up the picture and will only cover part of the page width.

Can you please help?
