Slider Widget not working with UberMenu

I’m loving PageBuilder and Widget Plugins. It’s phenomenal. I was admiring my beautiful new slider when I notice that it doesn’t get along with UberMenu. If you load my site and, before the slider changes, hover over a menu item, the dropdown from UberMenu goes behind the slider. How do I fix that? It fixes itself when it changes, but I need it to work from the start.
Thanks!
