I am having problems with Column Toolbar settings. I have a two column row and want the columns side by side in desktop view but stacked one on to of the other in mobile view. There are instructions in the documentation for applying different settings via the options to different grid breakpoints, but when applied to one breakpoint, The change is applied to all the breakpoints. The same happens if the column helper/clearfix is applied to the mobile breakpoint in options - all breakpoints are affected. Is the options panel broken or am I missing something? Hopefully someone can advise.
