Clarity on displayRole and displayFormat

Okay, so its purely to do with passing the composer as a field that can be displayed, completely separate from the index, okay I get that.

You can check the metadata that Kinsky is receiving by right-clicking on a track and selecting Details.

This doesn't seem to be the case all songs have the artist set, and you can see in this screenshot that Kinsky has received the (track)artist.



Also note for this release there is one single movement work, so this has not been grouped and this correctly displays the artist value.



I then tried adding Artist.displayFormat={$artist} to tagFormat this made no difference, the single track was still corecct and the grouping incorrect.

I then tried changing Artist.displayFormat={$orchestra}. The single track now displays orchestra as would be expected, but not no affect on tracks in grouping. But its not always wrong with grouping because I have another album with two groupings, tracks in first grouping is correct but not second grouping.
