You must click on the Save button or press GREEN (F2) to save your settings.
More than likely the user running either mythfrontend_qml or mythlauncher_qml does not have the right permissions to shutdown/reboot. You will need to edit the sudoers file to give it permission. See the instructions here.
The current behaviour assumes the system is a frontend only with no mythbackend running and will shutdown even if the backend is busy recording!
Better cooperation with mythbackend if it is running on the same system.
