pna-x power leveling for imx spectrum channel

Hello,

I have a question on the power leveling for the pna-x imx spectrum type channel. I am currently using the latest firmware of A.09.80.03. If you look at the attached picture, under the 'Tone Power' tab, there's a 'Power Leveling' section with 4 possible options. 

The problem I'm encountering is that once I change it from 'Set Input Power' to either 'Set Input Power, receiver leveling' or 'Set Input Power, equal tones at output' using SCPI commands, I can't change it back to 'Set Input Power' again. For example:

SENS11:IMS:TPOW:EQU ON

will allow me to change it from 'Set Input Power' to 'Set Input Power, equal tones at output'. But if I send:

SENS11:IMS:TPOW:EQU OFF

it doesn't change it back when I view it via the GUI. I also tried:

SOUR11:POW:ALC:MODE INT

and 

SOUR11:POW:ALC:MODE:RECEIVER OFF

separately but still nothing changes in the GUI. I am using the Agilent I/O Device Manager to send the SCPI commands out to the PNA-X. If someone can let me know how to change it back to 'Set Input Power' Power Leveling mode via SCPI, that would be greatly appreciated.

Thanks,
rok
