When I preview my site the hamburger menu changes its position... :(


What settings should I turn on to have identical design in the Designer and Preview mode? Currently, I have a problem with my hamburger menu icon. In the Designer everything stays where it should be, but when I preview my site, the button changes its position to the top of the screen… Can anyone please help me?

Can you add your read only link and site link please?
