Album Tracks Sorting Alphabetically?

[MrDJP]

I recently purchased a Matrix Audio NT-1 streamer, I was having problems getting it to work with my previous UPnP, server Asset installed on my QNAP NAS drive & saw the recommended UpnP server is Minimserver, so I downloaded the free version to give it a try. It synchronizes with my library without issue but I see if I browse by artist, their albums are sorted alphabetically & then when you select an album, they too are sorted alphabetically instead of track #. I don't believe this is normal even with the free version? All my files are FLAC, ripped with I believe the default dBpoweramp tag defaults. When I check the IDtags I think they are good, (sample attached) any help?
