Squeezelite plugin settings don't persist

Hey all,

I’ve got two Raspberry Pi’s setup with Volumio, an each has the squeezelite plugin installed.
However, no matter what I set the InstanceName to in the settings, the devices keep reporting themselves as “Volumio”, meaning I’ve got two entries with the same name - very hard to differentiate! I can rename them in LMS, but whenever a Volumio device reboots, it updates to the original “Volumio” name.

If I have a look at the squeezelite.service file, as well as config.json, no where is the instance name I chose being set anywhere.

So - how do I change the squeezelite name of my Volumio without having to manually edit the files in /data/plugins/music_service/squeezelite ?
