Different Sidebar Settings for Paragraph for Different Breakpoints

[flips]

For a paragraph inside a column, I’m trying to set different settings for breakpoints XS, SM and MD. But it seems whenever I change Width and Alignment for SM, it’s changed for MD. And if I change it for MD, it’s changed to the same for SM?

Different Alignment on different viewports

Hi, I’m probably missing something obvious here, but it seems like I’m unable to align a button to the Left on LG+MD and Center on SM+XS. For some reason, either the same alignment propagates to all viewports, or only Left and Right are “sticky”, but in a total random fashion. I’ve recorded a screencast to show the behaviour, any suggestion is really appreciated! Screencast link: https://streamable.com/cmsukw (I’ve also tried with custom classes to no avail)

… And if I move the contents into a DIV and then add a class to that div, I can force the alignment etc. I want. But seems to me this is a GUI bug?
