To help out, late to the party I know.
One button is a toggle in or out.
i cant remember off hand which is which but one way is audit and adjustments and the other is diag.
once in the menu the toggle changes direction on scrolling.
options are changed from the start game button and confirmed with the non toggle switch.
on each aud adj menu the last option is expand selections. this opens up the whole menu.
hope this help anyone.
