Issue with duplicates when creating playlist

[eseb63]

Hello,
I encountered this issue for the Albeniz 2CD album from Ricardo Requejo, tagged like this:

• Suite espagnole Op 47 : 6 tracks with WORK tag
• Iberia suite B. 47 : 12 tracks (4 books of 3 tracks)
  - each Iberia track has a OVERALL_WORK tag "Iberia B.47"
  - each Iberia track has a GROUP tag according to his Book
• Chants d'Espagne op 232 : 5 tracks with WORK tag
  

DiscSubtitle tag (CD1 , CD2) for each track

• Iberia Books I & II on CD1
• Iberia Books III & IV on CD2
  

MinimServer settings:

• itemTags : Overall_Work
• indexTags : Work
• tagValue : Group.Default={Work}, Work.Merge={Overall_Work}
  

Browsing : Composer > Work (on Windows Kinsky)
as expected, i see 3 works:

• Suite espagnole Op 47 (one group)
• Iberia suite B. 47 (4 groups)
• Chants d'Espagne op 232 (one group)
  

When right clicking one of these works and choosing "play later", a playlist is created but this playlist duplicates 7 times (7x6=42 for Suite espagnole, 7x12=84 for Iberia, 7x5=35 for Chants d'Espagne)

I did test with a Carmen album, having the same structure : i get also a playlist with duplication (7 times)
I noticed the same behavior with Windows Kazoo or Linn App.
unlike Kinsky, Kazoo shows groups and detail so it duplicates Book I to IV with 3 tracks for each. Book I and IV have sometimes the 3 tracks duplicated.

It sounds like a bug...


Edit : i ripped 2 other albeniz albums from Alicia de Larrocha, containing the same works : so each work is now referenced in 2 albums.

with same browsing, i get now for the created playlists :

• Suite espagnole Op 47 : 392 (=56x7) items instead of 6 (Requejo) + 8 (Larrocha) = 14
• Iberia suite B. 47 : 672 (=56x12) items instead of 12 (Requejo) + 12 (Larrocha) = 24
• Chants d'Espagne op 232 : 224 (=56x4) items instead of 5 (Requejo) +3 (Larrocha) = 8
  

I join a copy of these albums (with 1 second extracts) and a copy of my profile to help you reproduce the issue.
