Airmatch only runs once a day to adhere to those parameters.
Make sure the min tx and max tx are set in the radio profile (ARM min and max are ignored when you have an MM).
To run the Airmatch process, SSH into the MM and type "airmatch runnow _______" When it is done, you should see it in "show airmatch solution"..
At that time, the APs would have been constrained to the power you configured in the radio profiles.
