Is this a bug in MSO64B during measurement badge readings for Maximum and Minimum

In the eScope screen capture image attached (Top MSO64B_Max_Min_Reliability.jpg): the Maximum and Minimum badge values report 268.1 mV and -272.0 mV respectively.
But just from eyeball measurement the Maximum and Minimum values should be around 2.7 V and -2.7 V respectively.

After turning off the scope, and restarting. The readings seem correct as seen in this image: Bottom MSO64B_Max_Min_Reliability.
I see there is a new firmware verison, so I will upgrade. But perhaps you folks could like into what makes these readings unreliable.

Is my scope flaky or is this a bug in scope firmware?

Hi Ive just had a look at your jpg unfortunately it appears that you misread the screen you have two channels open
Channel 3 and Channel 4 channel 3 is set for 100mV per division and channel 4 is set for 1V per div

The display is set to overlay mode

Channel 4 is active so that is why the graticule is set at 1v per div.

to prevent this confusion from happening again set the screen to stacked mode 
To do this double tap on the screen area to get the waveform view dialog box and tap Stacked  in display mode this will set up each graticule 
for the voltage that you have set for each channel. You could of course just hit the channel 3 button on the front panel to make channel 3 active.

Hope that helps
