Multi disc albums

[AllanM]

I am running minimserver on a QNAP NAS and HEOS app and HiFi Cast as control points.

I have several multi disc albums. I tag these with track numbers 1 - n on Disc 1, 1 - n on Disc 2 ... and tag the discnumbers 1, 2...

When viewing the tracks on these albums they appear correctly i.e. 1 - n (Disc 1), 1 - n (Disc 2).

Yesterday I accidentally had a few tracks on a multidisc album where the disc number tag was blank and the other tracks were tagged correctly.

When viewing the album tracks they were separated thus

>>[no disc]
track a
track b
>> Disc 1
track c
track d
etc
>> Disc 2
track n
track o
etc

This was ideal and allowed the playing of just Disc 1 or Disc 2. If I then correctly tagged the tracks with missing disc numbers the whole list then just appeared contiguously with no breaks between discs. This would be a very useful feature, is this just not working correctly or a strange bug?
