Assigning a Button a function on the remote

Having a bit of a brain fart here. Just did a fresh clean flash of my box but i didnt save the settings. Now Im trying to assign the power button on my remote the deep standby function. When I assign it I the press exit on the remote. Im then asked "are you sure you want to cancel all the changes"

When I select No im then brought back into the Button setup menu - but how do I exit and save?
Because when I press exit it again asks me "are you sure you want to cancel all the changes" and if I press yes this time it will exit the menu but not save my changes?

I know im doing something stupid!

thanks
