you should’t edit in my-address.php should edit in “class-wc-shortcode-my-account.php” page.

where you can fine a code

if ( ! $value ) {
	switch( $key ) {
		case 'billing_phone' :
		case 'shipping_phone' :
		$value = $current_user->phone_4;
					break;
					case 'billing_email' :
					case 'shipping_email' :
						$value = $current_user->user_email;
					break;
					case 'billing_country' :
					case 'shipping_country' :
						$value = WC()->countries->get_base_country();
					break;
					case 'billing_state' :
					case 'shipping_state' :
						$value = WC()->countries->get_base_state();
					break;
				}
			}

instead of this ‘$current_user->phone_4;”

use your phone field name.I got the answer.
