This normal for the "SCN ADC" menu entry. I didn't try to do averaging 
or hysteresis on this reading because it would be overkill (it's 
strictly for test purposes). Each switch's reading has to fit into a 
"bin" that's about +/- 3 counts, and your readings were well within 
range.

That sounds like switch bounce. I do debounce the switches in firmware, 
but it's possible you have the 1 in a million switch with a slight 
deformation in its carbon contact or polydome. Customer support can 
arrange to get you a new switch matrix for your front panel, if 
necessary.
