Qnap : config file overwritten

[Heathcliff]

Hello again,

when i edit minimserver.config on a qnap server, some lines of the config files are overwritten when the server restart.

for example, when i change the lastIndexTags to :
minimserver.lastIndexTags = Artist, Genre, Conductor, Orchestra, Date
it change back to :
minimserver.lastIndexTags = Artist, Date, Genre, All Artists, Composer, Conductor, Orchestra
when restart.

how can i avoid this ?

BTW is my config file looks correct ?

minimserver.contentDir = /share/Classique
minimserver.license = 0.8.1
displayName = Classique
.logFile = /share/Public/minimserver.log
minimserver.lastIndexTags = Artist, Genre, Conductor, Orchestra, Date
minimserver.lastItemTags =
minimserver.relaunchScan =
minimserver.tagOptions = Album.sortTags\={Album, Artist}
minimserver.udn = 0b15f9aa-ff2e-49f9-b69e-66e3f6ef1b19
minimserver.previousAlbumArtistDisplayRole = true
minimserver.tagCustom = AlbumArtist.displayRole\={artist}, Composer.displayRole\={artist}
minimserver.tagFormat = Artist.displayFormat\={$artist$conductor$orchestra$date^^^ | }
minimserver.configVersion = 0.8.131


thank you very much !
