Mega menu not clickable on hover

I’ve set up one of the items in the top nav to be a mega menu but a lot of people are getting confused because unless you click on the top nav menu item (About Us) first, you cannot click on any of the submenu items. Normally, when a submenu opens you can click on the items even if you’ve just hovered over the main menu item. (yeah, I know, not a great explanation! - the site is here https://sherlocktree.com and I’m talking about the ‘About U’ in the top bar menu).

Any ideas for why this is happening and how to make the mega menu items clickable with first having to click on About Us (which most people aren’t doing - they’re just telling me the menu doesn’t work).

Thanks!
