Page overlay with slide in

I am using my subscriber Hustle Pro on another of my sites, and the slide in appears fine and does not produce a transparency overlay on the rest of the page. This is the expected and prescribed behavior.

I am using basically the same settings, using Free version on my work site for a single slide in; however, when it appears, it causes a full page overlay (darken the page behind it) like a pop up normally does. This is unwanted behavior for a slide in and I can't find any setting to remove the overlay when the slide-in appears.
We are using the Uncode theme and I cannot allow remote access unfortunately.
Am I missing a setting, or is this normal behavior for the free version?
