Multi Disk Album Track Numbers

[CleverId10t]

On the current 10.10 beta Docker release on Ubuntu 22.04 with HWE kernel 

All testing is on a completely clean instance with no additional plugins installed and with a test library.

My music collection is from CD's ripped to Flac with Exact Audio Copy, and then tagged via Picard using the below "script"

%album% $if2(%catalognumber%,%barcode%,%asin%)/
$if($gt(%totaldiscs%,1),%discnumber%-,)
$if($and(%albumartist%,%tracknumber%),$num(%tracknumber%,2) ,)
$if(%_multiartist%,%artist% - ,)
%title%

I'm seeing some albums where the multiple disks are shown correctly in Jellyfin, but for others the multiple disks are not shown but instead, the name of one of the CD's is shown

As an example https://musicbrainz.org/release/904a281b...6777e48aa0 is shown as "Tracid Traxx Compilation Vol. 2 CD 1" and has a single track listing with duplicate track 1, track 2 etc.

From the Jellyin logs, I see "Discarding ID3 tags because more suitable tags were found.", but no errors.

It is possible to manually edit the metadata of each track in Jellyfin, but I would prefer to find an automated method if at all possible.

To be able to provide a sample of all of the tracks, I tried chopping all bar the first 5 seconds of audio of all of the tracks with the below (from a shell in the Jellyfin docker container using the Jellyfin ffmpeg), but the chopped versions does not display the issue!

Code:

for f in *.flac; do /usr/lib/jellyfin-ffmpeg/ffmpeg -i "$f" -ss 0 -t 5 -c copy "chopped/${f%.flac}.flac"; done

Any suggestions on how to progress with this would be welcomed.
