Think I missed important part of log, so here's the rest:

Dump of metadata (ffmpeg -f ffmetadata):

TITLE=Shine

Also of interest is the fact that Logitech Media Server, which is running on the same machine as Serviio, has no problem with these tracks (there's more than one track of this album being bounced by Serviio for some reason).

This turned out to be the 'part #' (otherwise known as 'Disc #').
Looks like there's a bug in Serviio when a part number is included in the metadata.
I have raised Issue #767 in BitBucket.
