Ghosts of login items

[Mrpower]

Hello All

I have a staff member with a MacBook Air MacOS 10.13, encrypted and managed. In the past I have added a profile to the Mac, from profile manager telling the Mac to auto mount a shared drive at login. The staff member who used the laptop has become unhappy with the login item / auto mount. I removed the auto mount off the laptops profile. However even after removing the auto login manually it still wants to auto mount the shared drive at login ( even after a reboot). I am thinking it might have something to do with the encryption or it has some kinda of phantom preference / plist hiding in the library somewhere. Dose anyone have any ideas or solutions?
