Dropdown menus not showing on mobile but do in designer

PLEASE can someone help me. I AM going CRAZY!!
WHY is webflow so bloody difficult to fix problems? I’m wasting so much time trying to figure out problem after problem and getting nowhere! I’ve spent hours and hours and just can’t work out why none of my dropdown menus show up in mobile but they work fine in the designer. How can this be fixed? I’m beginning to hate webflow.

video to prove it all works in designer but NONE of this works on mobiles!!
