Kodi doesn’t see my music files

I have a windows 10 system using Jarvis 16.1.
When I add a source I see all the folders ie.. flac, hi-rez etc.
All the album titles are there but inside the album folder there is nothing ?
I have all kinds of music files from dsd to flac to mp3.
All my movies and concerts are working fine.
When I look in the folder from windows all the files are there but Kodi doesn’t seem to see them
What could the problem be ?
