Contact Tracking Issues with M 6.0.4

Your software
My Mautic version is: 6.0.4
My PHP version is: 8.2.29
My Database type and version is: 10.6.22 Maria db

Your problem
My problem is: Contact tracking for a particular contact reverted to me. So all my visits show up as contact having visited my site.

Let me quickly explain. I have client - LM, who was tracked as having subscribed to my funnel. For whatever reason, unknown to me, every single one of my visits now gets logged as LM. So when I visit my site, I see that LM has visited my site. It’s almost like the cookie for LM got transferred to me. I don’t know LM, I don’t share an ip with LM, I don’t know how his tracking got transferred to me.

These errors are showing in the log: None

Steps I have tried to fix the problem: Clear the Mautic cache by deleting cache ‘prod’ folder. Still, every one of my visits to my site gets logged as LM.
