Subsonic 6.1.5 (build 759abe) Network Monitor gone

[Blarks]

Hi,

my Network status under More, Network Status, Monitor is gone.
instead there is just a Playlist generator, I never used.

I tried rebooting the Linux Debian VM on where it runs, but that did'nt help.

Anything else is working perfect.
