Stacks 3.2.0, ExtraContent + RW 6.4 and Backgrounds

Hello- Not sure why, but background or image color to any Extra Content, it is no longer showing up. I’ve spent hours trying to figure out what is going on and why. Used to work fine. Recently updated to Stacks 3.2.0- Could this be causing this problem? Tried within ExtraContent v. 1.0.3 and ExtraContent Plus v.1.0.1 and nothing can be changed. I’m using Michael David Design’s Endeavor theme.

Any thoughts? Thanks!
