BQ34Z100: Data retention during power cycling BQ34Z100

Part Number: BQ34Z100

Hi team,

I was successful in calibrating the fuel gauge bq34z100 to my required values and it shows pretty accurate voltage and current values. The issue is all those set values reset to default when I power cycle the fuel gauge. The data flash parameters remain intact but the calibrated values are lost and I have to recalibrate the gauge to see correct values again. 

Kindly tell me what can be the reason for the fuel gauge to not be able to retain the calibrated values.
