Sections background choice does not work with light weight grid columns

Hi Tom,
I am working on a development and sections+grid columns plugin worked well on the home page until the last section. There it just shows default body background color allthough I called for bg color and same color bg image file on seperate occasions and even both at the same time to try. All works if I use a table instead of grid columns but then I cannot get rid of the margin from the table don't matter how I try and I need the map filling entire right part. This is the actual home page and the section that gives me grief is the very last one before footer

I copied this page somewhere else to see alternatives but the section back groun color just cannot be called. Is there a way to force the color change perhaps adding couple of lines on the simple css to force the body color to change for that section? At the same copied page I have tried using 2 footer widget area widgets instead of sections but in there I could not get the footer widgets stretch full width again (can this be because I set it up as single container in the customizer thus inheriting container width?)
This the test page where I have been trying to either force the bg color for the section or the container width for the footer widgets.

PS. I have tried with shortcodes uştimate and another columnizer plugin after deleting light grid columns code and same thing happened on the last section. So I guess it is not realy an issue with light grid columns
