Help with Space between Sticky Item and Navigation/Primary Menu

Hello, I have used the plugin to make an row module that I made in Divi into a sticky item; however, the item is being overlapped by the primary menu/navigation menu. What CSS or code snippet can I add so that the sticky item presents right beneath the primary menu/divi navigation menu? I successfully added the px value for for the item to become sticky on scroll, but I’m having a hard time figuring out how to figure out the primary menu and sticky item overalpp issue.

Thanks for your help!
