Bumping an old issue as I am seeing similar behaviour all of a sudden in Mautic 4.4.1 I have two new contacts created. There lead ID are consecutive: 483 and 484. For lead id 483 this is the audit log: ![Screen Shot 2022-11-30 at 9.21.00](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/4/4293ec2e8d6301fb6bbec4546ea57a1b283ab3a5.png) In the history of this user I am not seeing any tracking, however they are getting an email sent and changing into different segments and campaigns. For lead id 484 this is the audit log: ![Screen Shot 2022-11-30 at 9.28.38](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/9/98dd2be7c32e69dadb8afa79b1e9f393af06bfd7.png) For this user I am seeing a full history of all pages being tracked as well as emails being send. The emails being sent are from within a campaign and they are market type “marketing”. The field for email is publicly updatable and is also a unique identifier. ![image](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/b/b683eae310bfd1cec2f3a692f6e663afe1939515.png) The user is being created via the Mautic tracking script and/or via forms in both cases. @joeyk or anyone else looking for some interesting insights here. My initial hunch was that a field was being overwritten on a specific user, but I would expect to see the values of email change in the audit log if this was the case, and then the fact that the lead\_ids are consecutive also raises a small alarm. --- _[View the full topic](https://forum.mautic.org/t/how-did-happened-duplicate-contact/24575)._
