Album does not show up

One album in my NAS library does not show up in Audirvana (Windows version)under Album, Artist or Tracks. The metadata looks good when I check in dbPoweramp / Perfect Tunes. Any idea what’s up?

Hi!
Maybe a problem with characters used in file name? I experienced the case where some accent (French names) were used and not really recognized by Audirvana.
Can you try to add one track to the current playlist: if track cannot be copied to the playlist, there is probably an issue with the file name.
What does not help is the absence of log file (AFAIK) to help in understanding why some files are not imported.
