If you want to change one of the Attributes you need to highlight that line and then click "Edit Selected" at the top. You can then change the value and save.
These changes will affect the operation of the LUNA server. Only Super Admins can see and edit these. Do not make any changes without proper knowledge of what you are changing.
Most changes here require restarting Luna 7.
