GNOME Files 3.26 not respecting “Sort folders before files”
 

I am running GNOME Files 3.26 as my file manager. An annoying problem is that I would tick the checkbox "Sort folders before files" in the Files Preferences window, but this setting is never retained! Whenever I restart Files or even open a new Files window, the box would become unchecked.

How do I troubleshoot this problem so that Files remembers that I globally want to sort folders before files? Also, can this be applied to the file save/open dialog? Thank you.
