We have setup no admin accounts to segregate the view for our users. Our main Admin account can view all devices/sensors and then we have a normal user account that can only view set devices. However when logged into the user account it will randomly pick up alarms from devices in groups it cannot see and when looking at the devices page the devices will appear. Even though as stated this user account has no rights to see this these devices. We are using version 18.104.22.16865 x64 of PRTG. Many thanks.
