Man menu does not work properly

Hi all,
I use the ExpoSure theme and am having trouble with the main menu.

There are 2 menu-items that both link to a different page but when i click on them they both direct to the same page; the page that is set as Home.
The menu-structure in ‘Appearance’ looks good to me.

The website is: https://www.goquidditching.com/

I have set the ‘What is Quidditching’-page as static startpage.
But, when I click on ‘More Quidditching Pictures’ in the main menu I am directed to ‘What is Quidditching’ as well.

The Top-Menu works fine by the way, but I prefer the main menu.

Can anyone help please?

Thank you

Ron
