Files not seen by server NAS

[mclev]

I've looked at the log provided by MinimWatch and there are no errors. Since my last message I deleted all music files from the QNAP, then copied in 77 albums. I rebooted the QNAP and reloaded the MinimServer list on the Lumin iPad app. This time the QNAP file list and Windows Explorer are the same. But only 69 of the albums are available via MinimServer on the Lumin Ipad app. For example a David Crosby album does not show up in any view I've explored: artist, album, folder, etc. This particular album is a download from HD tracks, fully tagged and has worked in the past as a computer file played through JRiver.
