Track number missing

[Alandbush]

I am not aware of any MinimServer feature that can provide the information your require.

It may be useful to try another control point, other than the Samsung, to determine if the behaviour is consistent.

For example, Kinsky for the pc, or BubbleUPNP for an android device.
If necessary, both of these control points can display each tracks' metadata, such as TrackNumber and file name.
