BQ40Z80EVM-020: XDSG and DSG not toggling on command

Part Number: BQ40Z80EVM-020

Tool/software:

Hello,

Before when I used to send 0x0022 command the CHG and DSG would toggle now only the CHG is toggling. And when the FET is in OFF state and I send 0x0020 for DSG toggle only the DSG_Test toggles not the DSG and XDSG. WHat is the issue here? 
I have attached the bit registers screenshot for your reference.

This one where only DSG_Test is toggled not DSG and XDSG when the FET_EN =0

This is when the FET_EN=1 the CHG=1

What may be the issue for not toggling the DSG?
