Central movieset location not working when movieset not on tmdb

[hablaras]

I have this in settings.xml

<setting id="centraldir.set_dir">/var/media/MOVIES/moviesets/</setting>
<setting id="centraldir.set_enabled">true</setting>

And have a movieset for a movie in .NFO called XYZ, which is working in Kodi.

These files exist:
/var/media/MOVIES/moviesets/xyz/poster.jpg
/var/media/MOVIES/moviesets/xyz/clearlogo.png

But when using Manage -> AB: Add missing artwork on the movieset, it reports, "No artwork found. Missing something?"

The log reports that the set cannot be found on TMDb, which is correct. But it doesn't mention that it scanned (or tried to scan) the central folder:

== 2021-02-09 15:30:09: Processing list automatically
1 items in list - set: 1
== 2021-02-09 15:30:09: Processing set 'XYZ'
Missing artwork: clearart, discart, fanart, poster, keyart, banner, landscape, clearlogo
No artwork updated
Encountered an error - Could not find movie set on TMDb

Is this the expected behaviour?

That doesn't sound right. I'll take a look.

Small update:

• It creates new movieset folders, but only when the movieset has not previously been added to the MyVideosXXX.db database. Setting a movie folder content to None and removing all movies, does not remove the moviesets from the movieset table! So it only works for a completely new set of movies with moviesets that have not ever been processed before
• The folder names are case-sensitive: so a folder named "star wars" will not be matched by movieset "Star Wars" in Kodi
