What is the customer policy with respect to WIPS that you are trying to achieve?
Is there something specific in the 'high' profile that the customer wants enabled?
An over vealous configuration of WIPS policy can have a detrimental effect, even to your own legitimate ssids, as cjoseph mentioned.
I would suggest starting with the 'low' profile and tuning up the features that you require.
Nevertheless, I believe that the 'privacy' setting in the unauthorised-device-profile is what is causing your issues, though the logs will confirm that.
