Upfront non-responsive background image

Hello,
I've just started using Upfront, been reading the docs and kicking the tires. I have a temp site that I'm building to test it out, and I've run into an issue I can't figure out. Specifically a background image in a region that isn't responsive.

If you look at the site, I've actually placed the image twice, in 2 different regions (stacked on top of each other) with different settings, and one with elements. Neither version is scaling when I resize my browser or when using responsive mode.

What am I missing? Thanks.
Jeff
