Mega Menu

I am using Barberry theme, it comes with a mega menu.

In ‘Menus’, I have set up my menu structure to have categories as a mega menu.
But online, it doesn’t work.

Here is the website: https://www.girleewoo.com.au/woo

and here is a screenshot of backend:

Can anyone see what I’m doing wrong?

Thanks for any help ??
