Solid background behind header on Static Home Page won't appear in Pro Version

I first tried out the Free version and was very happy with the theme, so I purchased the Pro version earlier today. One difference that I have noticed that I can’t figure out how to fix is when I am using a header image sitewide and scroll down the static home page, the solid black background does not pop up behind the top header navigation menu when you get below the bottom of the header image like it did on the lite version and like it does for all of my other pages. It is frustrating because the menu text disappears when I get to the white background of the page. I’m working locally, so I can’t share a link but here’s some screen captures:

Behavior Working Properly on Interior Page:

Black Background Doesn’t Appear Behind Header Menu on Home Page:

When I activate the lite version of the theme, that black background does appear when I scroll down on the home page. Is there a setting in the customization that I could be missing?
When I switch back to the Lite/Free version, the behavior works on both the interior pages and the home page. Any help would be much appreciated!
