XEM7360 VADJ values not settable

I am unable to set the VADJ values and mode for the XEM7360. Using frontpanel device settings I can enable or disable the fan using XEM7360_FAN_ENABLE, however when I try to set VADJ 1,2, and 3 to 3.3 volts by setting

XEM7360_VADJ1_VOLTAGE 330
XEM7360_VADJ2_VOLTAGE 330
XEM7360_VADJ3_VOLTAGE 330
XEM7360_VADJ_MODE 191

Nothing happens.

I also tried accessing the settings using python

import ok

dev = ok.okCFrontPanel()
dev.OpenBySerial("")

# Populate DeviceSettings struct
s = ok.okCDeviceSettings()
dev.GetDeviceSettings(s)

# Adjust settings
s.SetInt("XEM7360_VADJ1_VOLTAGE", 330)
s.SetInt("XEM7360_VADJ2_VOLTAGE", 330)
s.SetInt("XEM7360_VADJ3_VOLTAGE", 330)
s.SetInt("XEM7360_VADJ_MODE", 191)

# Confirm settings
print(s.GetInt("XEM7360_VADJ1_VOLTAGE"))
print(s.GetInt("XEM7360_VADJ2_VOLTAGE"))
print(s.GetInt("XEM7360_VADJ3_VOLTAGE"))
print(s.GetInt("XEM7360_VADJ_MODE"))

# Save settings to the device
s.Save()

Which prints the correct values, but I can see in the FrontPanel sensors display that VADJ is still stuck at 0.8 V.

How can I set VADJ to 3.3 V?
