Display trakck artist for compilation albums

[GPOJim]

I've very recently installed MinimServer on my QNAP NAS so am new to the product.
I've seen this question asked and answered several times in the forum but I've not understood some answers and tried to apply others without success.

I have chosen to have the <n>Albums view divided alphabetically.
When I select <n>Albums from the top level, then the first letter, then the compilation album I see the list of tracks.
But the artist shown against each track is the album artist (usually 'various artists') and not the artist performing the track.

When I choose the AllArtists view from top level I see that the track is correctly shown against the track artist's name indicating that the metadata field is correctly filled.

I'm sorry to put this question yet again but if anyone can walk me through a fix for this I would be delighted. Twonky by the way, also installed on the NAS and working on the same folder set of music, gives the correct track artist name when an album is selected.
