save Text List field using update post meta

Dear Support,

i have a text_list in my admin custom post type and i am trying to set the values using update_post_meta.

this is my field:

array(
                    'id' => $prefix . 'address',
                    'type' => 'text_list',
                    'name' => esc_html__( 'Postal Address', 'nw' ),
                    'options' => array(
                        'address_1' => 'Address Line 1',
                        'address_2' => 'Address Line 2',
                    ),
                ),

$prefix = 'pph-';
update_post_meta($applicantID, $prefix . "address", 'one');

i tried the above and it sets the value for both fields. address_1 and address_2

i also tried below with no avail
update_post_meta($applicantID, $prefix . "address[]", 'one');
update_post_meta($applicantID, $prefix . "address[address_1]", 'one');

thank you.
