Logitech Media Server: Playlist not found

[hestia]

I've a DzVents script to play my LMS
I've some playlists that are playing well and others not: not found
My LMS is running on a dedicated RPI and my playlists are on a NAS (Synology)
The LMS use cifs to find the playlists with this options file_mode=0777,dir_mode=0777,sec=ntlm,iocharset=utf8,vers=1.0
The user (erato) is grated on the folder with full privileges
The folder has the following permissions:
drwxrwxrwx+ 4 root root 4096 Jan 19 14:43 musicPlaylists

The playlists have the following permissions:
-rwxrwxrwx+ 1 erato users 14777 Jan 19 14:39 France5.m3u => error
-rwxrwxrwx+ 1 erato users 14777 Jan 13 2018 France.m3u =>> works well

Error: Logitech Media Server: Playlist 'France5' not found.

What is strange is that some playlists works well and others not.
What is more strange is that if I copy a playlist (Linux copy) that works well to another file, so with the same permissions, the new playlist doesn't work. I had previously made a full Clean library and rescan everything, and also restart LMS
