Gio console takes over from RPU3

Hello All,

I have a question about GIO console

It was okay before, when I set GIO console as a primary, RPU3 as a back up. When I exited RPU3,lighting status stays on. Is there any reason why the lighting status goes off when I exited from RPU3, even I have a same setting for GIO console as primary this time?

much appreciated in advance
