I have tried all the suggestions, so I don't know what I'm missing. Whenever I edit one of my smaller breakpoints my default breakpoint also adjusts. All elements are nested correctly in the DOM. I click on the name of the breakpoint, the canvas resizes. Overrides to the default style should highlight in purple (breakpoint color) but this is not happening. I have been working on this for two days with no success. Any guidance would be appreciated - except for Check the DOM - did that!
