Mobile Menu (right over) broken in designer view but works in browser

Hi There,

I am new to webflow and currently demoing the product with a view to using for our companies website. I have built a menu and added a dropdown. within the drop down I have added two columns to display sub menu items.

When I go to a browser on desktop the menu opens as it should and drops down the sub menu.
When on mobile, the menu displays as an ‘over left’ menu and behaves as expected.

When I open the layout in designer its broken and does not reflect the mobile menu. I am unable to continue designing because it’s so different. I hoping this is a bug and someone knows how to fix!

in browser behaving as expected

in designer
