Hello Niche Footer Background Image/Alignment Issue

I can’t figure this out and boy have I tried! I feel like I’ve spent the last hour meticulously going through code to figure out what is happening as well as all the non code settings and can’t get it fixed.
My footer alignment on the left menu is aligned all the way over to the left of the browser. When I try to adjust the settings to bring them closer to the center (like in the demo), it either only works if I make the background not full width or it doesn’t change anything at all. I’ve attached a screen shot of if I leave it full width. Any help would be greatly appreciated.
