Hi!,
I also have a problem with the “Hide on screen” settings “Content Editor” and “Page Attributes”. If I linked fields group to a specific page, it work as expected. But if this specific page as a parent, the “Content Editor” and “Page Attributes” are shown even if I checked them in “Hide to screen” settings.
I have the version 5.3.1 and my fields group contain a repeater field, if it can help.
Thanks! 🙂
