WordPress Menu and positioning sub menu

Hi all,

Just a quick, hopefully simple question here.

is the the page in question.

Im using Beaver Builder to build my website just in case thats important.

The issue im having is with the menu at the top of the page, the ‘People’ link has a sub menu beneath it, but that sub menu is appearing underneath the ‘blog’ link when i mouse over People. I found the element in chrome using the Dev tools and managed to apply a change in there to see what i needed to edit. The thing is now i have tried to select it that many different ways now with CSS it just doesnt seem to want to work.

Which part of the menu would i target with CSS? It is a wordpress menu by the way. I thought targetting .sub-menu would have worked but it hasnt.

Hope someone can help, thanks!
