Problems With Tag Property tagOptions

[resmuc]

Hi,
I'm a happy MinimServer user (so far) and decided recently to dig into the tag property universe. I found that some features sounded helpful to me and configured them. The results were ambivalent and I don't know whether I made mistakes or wrong assumptions.
I use Minimserver 0.8.5.3 update 134. The MinimServer runs on a Synology NAS within a LAN.
The database contains about 600 albums and 2000 single tracks.
UPnP client is MediaMonkey and Cambridge CXN V2 Network player app. Other clients (VLC, MusicBee, AIMP) do not allow to configure media server access or do not react on the MinimServer configurations.
I use mp3tag for tag editing.
tagOptions Artist.ignore.sort={The}
The database contains about 70 artist names starting with "The". Before activating the property change, I copied a new album with artist "The Temptations" to the database.
Observations:
The new album was visible in MediaMonkey only after MinimServer restart with property statupScan=full. startupScan=true as well as MinimServer rescan where not sufficient.
The tagOptions command only works on the recently added "The Temptations" album and on on all single tracks from artists with names starting with "The". All albums remain unchanged under "T". In all tracks (single and albums) the Artist tags as well as the Album artist tags are set.
Where is the mistake in that scenario?
Thanks and regards,
