Hi!
I think that the stylesheet files are cached, perhaps on a CDN (cloudflare), as the back-end was showing the correct configuration, however the front was serving an older version of the stylesheet file.
To bypass that for now, I have enabled this option: https://i.imgur.com/F03BNhZ.png
I am seein the same layout as on the back-end preview window now. In case you have a CDN/cloudflare cache enabled, make sure to clear it, after making changes. It should be okay now.
