i think this is the same bug as in this thread: Stacks 4 update - my 2 x columns are all stacked as if on mobile
It’s a problem with RW7 Preview mode (in the app or in the browser – doesn’t make much difference) – but it should not be a problem in edit mode or the published page. RW7 Preview has a unique folder structure that Stacks 4.1 isn’t accounting for correctly and didn’t get picked up in my automatic testing. Sorry about that. I should be able to correct this in v4.1.3
If you’d like to keep track of my progress on this, I’ve filed it here in our public bug tracker.
