Tracking emails send from Mautic

I added 2 contacts in Mautic (2 collegues of me) and send out an e-mail with a link. The goal is that when the contact clicks on a link and visits a certain page on a website a second e-mail will be send to the contact.

The problem is that the tracking works but the visit to a certain page is being tracked at the wrong contact. So when contact 1 visits page www.google.be the tracking is reported in contact2. The 2 contacts are working in the same network, could this be the issue?
