The tests we ran internally showed that uniques where being logged correctly. Could you send me your account details including email address used to register and the domain name or URL of the site you are running on so I can take a look at the account:
Anyway I think the problem may be that visitors aren’t being logged as real visitors or aren’t staying on the page long enough. Are you sending traffic to your domain from auto-surf type websites? If so this is not allowed on the system. If the traffic is real then it could just be that users are closing the page before the scripts load and the privacy notice is displayed.
