Disregard my previous reply. While what I wrote is true for some parking programs, it's not true for all - Parked.com for example doesn't require the domain in the CNAME.
More to the point, don't add the affiliate name to the Webcams CNAME ...
instead use www.webcams.com ... I notice you're using webcams.com without the www - that may not the same, so be add the www. part to the CNAME and see if that helps with tracking.
Be sure you've entered your "host" name (website domain; without the www part, but not sure which is preferred) in the white label control panel.
It's possible there's a bug in which www. prefixed (or vice-versa) host names are being treated as separate. Hopefully someone from Webcams can chime in and explain the preferred format for entering the host name(s) and how www and non-www host names are treated ... ideally as being the same, since most often traffic will come in on both ... ie. example.com and
www.example.com
