Transmission plugin won't work on OMV 4

Hi, i tried everything but no way to set it up...
The problem is that when i try to set the download folder, when i click the save and apply button it return this error :

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; omv-mkconf transmissionbt 2>&1' with exit code '2': /usr/share/openmediavault/mkconf/transmissionbt: 60: local: NAS-GN41/Shared: bad variable name

Also i gave permissions to debian-transmission and serched all over the Internet but i can't find a solution..
Is there anybody who can drive me in the right direction to fix this trouble?

Thank you all in advance

So nobody able to help me? Please guys...

Help help help!!!

Thank you for the support, well i tryied everithing with folders also but nothing, the error stay..
At the end i uninstalled the plugin and installed Transmission + OVPN by Docker and everything works pretty well.
