miniDLNA db don't refresh

I currently run miniDLNA plugin 1.1.7 over Volumio 2.282 on Raspberry Pi 4B.
I have set the miniDLNA folders on my NAS shares mounted by Volumio: /mnt/NAS/music, /mnt/NAS/pictures & /mnt/NAS/video.
It seems that the database never refreshes - even when I click on “Rescan” - and stays eternally in the state it was after installing the plugin
I also tried “sudo minidlnad -R” and “sudo service minidlna restart” without success.
Thanks for your help.

did you see your typo? sudo minidlnad -R

yes, it is a copy/paste error
