[Bug] Trying to change lib folder structure, losing affected metadata as a result

Initial path:

[details=“Note, another bug on screenshot (posters are portrait, I was creating “Other videos” type lib)”]
When changing default “Plex Video Files Scanner” to “Plex Video Files” one, upon save library type resets to “Movies” from “Other Video” that I created. You have to (during same edit) uncheck some other option on the same page, forgot which one, probably generation of thumbnails.
I had to switch agent to “Personal Media” to revert. This happens all the time in recent versions. I have never reported it yet.
[/details]

Structure:

Scan + Empty trash does nothing.

Edit path, adding subdir from the same structure, no underlying filesystem changes.

Saving changes triggers auto re-scan, you may even see it scanning same locations twice:

No unavailable tag as expected:

Empty trash does nothing.
Delete old path:

Followed by auto re-scan:

Hitting Empty trash:

Alerts:

Manually hitting Scan, new metadata is generated:

Edit:

inserted missing “Media Info” screen
