Correct Display Of Music File Order

[AnnieBody]

I use MinimServer with StreamMagic.
My library starts and I open 'Folder View'.
From there I open a category 'Albums'.
If I open an album the tracks are displayed in track number order.
If I open a different album the tracks are displayed in an apparently random order.
Both folders have the file track numbers starting from 01 to nnn.

I then open another category 'A'.
None of these files have track numbers as they are singles.
All single categories display randomly.

What do I need to set in order to get all albums listed in track number order and all singles listed by 'artist - track'?

Regards
