Our site is https://sorpresas.mastercard.com/ar . The report shows the main referral domain to be http://mastercard.com , but once I check the specific urls under that domain I see all come from different pages within our own http://sorpresas.mastercard.com/ar  site. How is it possible that the referral sites listed be coming in from our own site?
