When you change the published year on a post and view it the categories and tags move to the far left. Changing the day works but when you change the year this happens. This site is local. I made a screencast.
Aha. Originally, GP would detect in BB was active, and if it was it would set the content to full width automatically. This was before the Page Builder Container meta box.
So, in order to preserve back compatibility, GP now checks if the page was published prior to the inclusion of the Page Builder Container meta box – if it was, it keeps the auto full width content.
Best bet is to just keep your published date current 🙂
