When using the radio I often press the lowest button (submenu) and assume to be able to go back a level in the menu. However then I see I am olmost removing a preset of a station. This is because when playing music this is the submenu button. This is not a logical setup.
Logical? Maybe, maybe not. But that’s the way it operates and to be honest you are the only one who has a problem with it or think it’s awkward out of literally thousands of others who have posted here.
