Using the Google Maps field to output segments of an address

The documentation for the Google Map field demonstrates a really nice way to render addresses using the address entered into the field.

<?php 
$location = get_field('location');
if( $location ) {

    // Loop over segments and construct HTML.
    $address = '';
    foreach( array('street_number', 'street_name', 'city', 'state', 'post_code', 'country') as $i => $k ) {
        if( isset( $location[ $k ] ) ) {
            $address .= sprintf( '<span class="segment-%s">%s</span>, ', $k, $location[ $k ] );
        }
    }

    // Trim trailing comma.
    $address = trim( $address, ', ' );

    // Display HTML.
    echo '<p>' . $address . '.</p>';
}

For my project I am working with small towns in the UK so city, state and country are not relevant. Instead, I would like to use postal_town and administrative_area_level_2 in place of these which should render the town and county respectively. So for the foreach I have

foreach( array( 'street_number', 'street_name', 'postal_town', 'administrative_area_level_2', 'post_code' ) as $i => $k ) { ... }

I had assumed that this would return: number, street, town, county, post-code. But the postal_town and administrative_area_level_2 both return nothing.

Printing the array keys using <?php print_r(array_keys($location)); ?> appears to show only a limited set of options.

I could as a compromise just use <?php echo $location['address']; ?> but this gives a slightly different version of the address (Business name, street, town, country), but it’s not quite what I’m after.

Does anyone know how would I go about getting my chosen values to render to the front end without having to resort to a separate address input field?
