Mobile size is too large that it overlaps with the desktop

We have 4 breakpoints set up in Builder:

Desktop: 1024 px+

Tablet: 768 px -> 1023 px

Mobile: 640 px -> 767 px

Mobile (XS): 639 px-

With these breakpoints, the Visual editor displays the desktop size next to the mobile one. The mobile one is too large that it overlaps with the desktop one and needs to be hidden and styled separately just on mobile to be able to work properly.
