Issues Updating Plex on QNAP 251

So every time I seem to “update” my plex server it seems to actually remove the old server and start a new one.

The old server even still shows under devices but obviously no longer works.

This means I then have to manually add all my friends back onto the “new” libraries/server.

Is this a known bug, or is it a PEBCAK error?

Thanks
