ADE5169 - VAHR register accumulates lesser value than WATTHR.

We are implementing a single phase energy meter design using the ADE5169. All initialisations are done, no gain or offsets are given but Irms registers an offset of around 1000 in the ADC 24bit register.

On loading and running the meter, the WATTHR accumulates a bigger value than the VAHR from the beginning and the gap widens as time progresses. I believe the VAHR should always be greater than WATTHR. So could you all please help me find what could be the reason of this error.
