[Bug] Photo folders - Changing Title automatically changes Sort Title

I’m getting my photo folders into a new organization, which involved renaming the folders to begin with the date, so a folder name might look like this:
20170529 - Sweet Creek

Plex, when rescanning the folders, of course used that as the folder name, which I don’t need to see at that point. So I just started changing the Titles on all my libraries to remove the date, but leaving the dates in the Sort Title field. After doing two folders, I see that the folders are being automatically moved to the end of the list, as if they were being sorted alphabetically without the dates.

When I looked at the settings for a folder that I just edited, I see that the Sort Title has been changed to match the Title, which is not what I did.

How it started:

What I changed:

What I found afterward:

Has anyone at Plex tried to reproduce this?
