Ghostery may be interfering with Credit Card Shopping Mall 'Points'

Edit Subject

Hello. Been using Ghostery for a year or so. I just noticed that every time I use redirected shopping, I'm not getting my 'points' credited. For example, if I'm on Chase Visa, and click their button to earn points at their 'online mall', ghostery prevents the redirect. If I click the ghostery icon to allow the redirect, and get to the shopping site, my points never get credited. I think there's a disconnect as far as Chase is concerned, between me clicking the shopping button on their site, and when ghostery allows me to get to the store that's supposed to credit me Chase points for a purchase. This has happened to me on Chase, United Airlines, and Shell Fuel Rewards. Was wondering if this has been reported by anyone else, since I've done the transactions on two different Win 7 machines with ghostery on them. Thanks.
