How do I decrease the gap between the menu and the body on the mobile site only?

Hello,

I’m trying to decrease the gap on my mobile site *only* between the button links and the dropdown menu/breadcrumbs. It looks fine on any other format just mobile there’s a big white gap and I can’t work out where it’s coming from.

The only difference between this and other pages is that it’s Full Width (Stretched) on the ‘Layout’ widget settings.

Thanks in advance!
