Battery volts don't change in tuner studio?

[waybad]

my battery voltage is 12v all the time? do I use the (calibrate battery voltage ) to make it read right? and if so what should be the numbers? right now the numbers are for ,,supply voltage at ZERO ADC count(v) is 12
supply voltage at MAX ADC count(v) is 12
I see at the bottom it says it should be 0.0 and 29.7.. wonder how mine got changed?

Thanks

TS MS(BETA) V2.6.19 ,,,MS2/EXTRA RELEASE 3.3.3 here is a datoalog,, it's has some popping through the exhaust.. and something crazy going on here,, but when I turn it off and restart the car it straitens out,SOMETIMES!!, but that is a different problem.. anyway you can see that there is 12v always and nothing else,, the alternator is putting out 13.8-14v at idle..
Thanks for looking

You already answered your own question about why the battery voltage is stuck on 12V.
