I have downloaded the Linux 64-bit version and, on adjusting the configuration, I see one inconsistency (which may not be new, it is quite possible that I have not noticed it before now).
My testing is with a G.992.3 (ADSL2) service.
Configuration ---> Items to Monitor.
Under the "pbParams (VDSL2 only)" heading, the "SNRM per band" option is correctly "greyed-out".
Configuration ---> Webserver.
Under the "Items to include (snapshots + html pages)" heading, the "SNRM per band" option is, again, correctly "greyed-out".
Configuration ---> Snapshots.
Under the "Autosave graphs:" heading, the "SNRM per band" option is incorrectly available for selection.
