SAF Phoenix M ACM config

Is anyone familiar with configuring ACM on the SaF Phoenix M radios. I have the liscense keys accepted and my settings are:

Parameter 1: 232Eth W 40mhz

ACM switch delay: 2000 ms

ACM switch CER threshold: 1e-5

Parameter 2: 192Eth 40 mhz

ACM switch delay: 2000 ms

ACM switch CER threshold: 1e-4

Revertive Switch Quality Threshold: medium

Parameter 3: 176Eth 40mhz

ACM switch delay: 2000 ms

ACM switch CER threshold: 1e-4

Revertive Switch Quality Threshold: medium

I have my SNR threshold at 18 db.

My problem is when ACM is enabled it always chooses the lowest modulation. My SNR when set to 232 is 21-22 steady yet it still modulates down. Any thought?
