Background image absolute is hiding dropdown nav menu

Hi, I’m using a hero image that is positioned with absolute, and a negative z index so that the main text sits on top. This is causing issues with my navigation bar drop down under Services. It is overlapping the dropdown and not letting it be displayed. Any ideas what I can do to solve this? I’ve tried changed what it is relative to but it doesn’t seem to be making any difference. Thanks!
