With the Default Breakpoint page is set up, I make changes to the Tablet Breakpoint Page. When I return to the format of the Default Breakpoint page is out of whack.
See screenshots of Default Page Before, Tablet Page, and Default Page After.
It looks like you’re trying to adjust the physical order of the elements (shown in the Navigator panel in the Designer) however these changes will affect all breakpoints.
To have changes cascade down like you’d expect, you’ll want to keep your changes reserved to the Style panel instead as these only take affect per breakpoint.
