The availability status for West US remains 'Single' despite adding a new checkmark in the adjacent column. If this new feature availability warrants a change to 'Dual' status (as occurred with Central India and Switzerland North), the status should be updated accordingly. Please verify if the availability status should also be changed to 'Dual'.
