Display Anomalies after upgrading to MinimServer 2

[JohnT]

I have updated my MinimServer 0.8.5.3 running on a Synology NAS to MinimServer 2.0.9 update 156 and updated MinimWatch to version 2.0.8 running on Windows10. So far so good.

As expected, I can browse my classical music library as before but I am seeing an anomaly on the ‘now playing screen’ on my control point when playing music. Some of the metadata is not being displayed as expected.

My music library consists of radio concerts/operas captured over many years together with ripped CDs and commercial downloads, all now in FLAC encoded audio files tagged with Vorbis comments using the Mp3tag application.

I have devised my own tagging scheme using both standard tag names and some user-defined tag names. I use the tagFormat option to build strings to be displayed in the ‘Title’, ‘Album’ and ‘Artist’ areas on my control point display. E.g. I don’t populate the TITLE tag in the audio file but populate other tags such GROUP, COMPOSITION, KEY, NAME, MVT and MOVEMENT and then use the tagFormat property to format strings for display :-

Album.displayFormat={$Album^$Date^ [^]}

Artist.displayFormat={$Orchestra^^, $Hon^^ $Conductor$Artist$Chorus}

Group.displayFormat={$Composer^^: $Composition^^$Key^ in ^$Name^ (^)}

Title.displayFormat={$Mvt^^ $Movement}

On the control point, before the upgrade, I would see for example :-

I. Allegro non troppo
Beethoven: Violin Concerto in D
The Hallé, Mark Elder, Viviane Hagner (vln)

After upgrading to MinimServer 2 the last line displays the composer name again rather than the artists :-

I. Allegro non troppo
Beethoven: Violin Concerto in D
Beethoven

Renderer : Cambridge Audio CXNv2
Control Point : Cambridge Connect app (android version on a Samsung phone)

I have experimented with the tag formatting but cannot reproduce the original behaviour. Any suggestions?
Thanks.
