User logon history - Agent Tray Icon

User logon history - Agent Tray Icon

Hello Support,

I have a question about the content of user logon history option in workstation agent tray icon,
I read from DC guide that when User Logon Reports is enabled, 
the user will be able to view his/her login history.


I tried to select this option from a client machine but I can't understand why there is logons from another machine, which is my domain controller as the image bellow shows,



Could you help me to understand that?
