MCU-PLUS-SDK-AM263PX: Problem with PMIC LDO4 not working in AM263Px ADC example on control card

Part Number: MCU-PLUS-SDK-AM263PX
Other Parts Discussed in Thread: AM263P4, SYSCONFIG

Tool/software:

Hey, I am using the control card to evaluate the AM263Px ADC example 
"adc_burst_mode_oversampling_am263px-cc_r5fss0-0_nortos_ti-arm-clang".
We believe it is necessary to use the LDO4 for ADC reference,
because the PMIC LDO4 is more accurate than the AM263P4 on-die reference.
To use LDO4 (1.8V) as the ADC reference, the switch SW9 on control card is set to pin 3 and pin 6.
I was able to turn on the PMIC LDO4 with the following combination.
(The LED LD20 on the control card lights up.)
  *SysConfig: 1.21.0
  *MCU+ SDK for AM263Px: 10.0.0.35
However, I cannot turn on the PMIC LDO4 with the following combination.
(The LED LD20 on the control card is not light up.)
  *SysConfig: 1.22.0
  *MCU+ SDK for AM263Px: 10.1.0.34
  (The PMIC settings have been deleted from SysConfig)
Please tell me how to turn on the PMIC LDO4 with the above combination.
Thanks,
T. Hirata
