Overflow in mobile

Normally I know how to fix overflow, but in this case I don´t know what to do. I tried everything from putting every section in to a div block wrapper where I set the overflow to hidden, to setting the percentage to 100%, playing around with vh and vw. When I make the Heading smaller it doesn´t fit my design properly but even then the overflow is gone in the webflow editor. When I publish it and look it up on my phone the overflow is still there, even tho it isn´t in the editor. If someone could help me, I would be very thankful!! Sorry for my english spelling
