Added margins in my color block show selected Logo Area Background Color

Hi,
If I add a top or bottom margin to my color block the logo area color I’ve selected for the site appears where my margin is. I removed all my Custom CSS on the site and my settings in General Styling but this didn’t make a difference. You can see the margin area I set up on my home page as a dark gray bar that is beneath my top header section (below the image header and “Request A Demo” button. How do I prevent this color from filling the margin areas? What do I do to remove this color in my margins?

Thank you,
Kristina
