station - last signal spectrum plot different

I updated my Blue to firmware 8.4 last night.  Last night I also noticed on my - station tab - Last Signal window that the signal spectrum is now
dominated by the electrical system 60-Hz and I'm sure the first few
harmonics too.  The real signal spectrum is hardly visible near the bottom of the plot. 
It appears to be a spectrum scaling change somewhere perhaps.  The spectrum also appears similar on
several other Blue stations pages.  Several Red stations spectrum I
checked appear normal and not dominated by the 60-Hz signal.  Not a big deal but
something changed, perhaps only for the system blue stations?
