Changing the charging voltage and charging current in the BQ27530EVM using the Gauge Studio

I am using Gauge Studio version 1.4.1 with an EV2400 and a BQ27530EVM.  The battery cell I have attached is manufactured by Hangzhou Wanma high-energy battery co LTD, model number PL703562.  The battery cell is unusual in that it uses a maximum charging voltage of 4.6 volts.

I am trying to change the charging voltage and charging current.  I had assumed that I had to change the Prog. Charger Voltage and Prog. Charger Current registers. However, when I attempt to change these registers (Expert mode) upon refresh the register values remain unchanged.

Can you tell me (step-by-step if possible) what I must do to change the charging voltage and charging current?

Thanks
