Duplicate tracks after editing metadata

[MartinBarrell]

I had added some albums to minimserver then subsequently changed the metadata (using Musichi tagger). One of the fields changed was "Album Artist Sort" which is an index field. I now see both the old and the new values in the index and when I select the albums I get the option to get the complete album I then see each track duplicated. I have restarted and refreshed minimserver and problem is still there.

Environment is minimserver 7.2 on QNAP arm. Control points seeing this issue Bubblesoft upnp on Android and Marantz MCR603.

Other albums are OK.

I would guess removing the tracks and re-adding may work but would be annoyance

Any ideas?
