无法从WooCommerce重命名邮政编码和城市标签字段

Question

I tried for more then 3 hours to change and to remove the red star* from the postal code, but does not work here is my code in functions.php, using a child theme

add_filter( 'woocommerce_checkout_fields', 'change_billing_codpostal_checkout' );
function change_billing_codpostal_checkout( $fields ) {

    $fields['billing']['billing_postcode']['placeholder'] = 'Introduceti codul postal';
    $fields['billing']['billing_postcode']['label'] = 'CodPostal';
    return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'change_billing_city_checkout' );
function change_billing_city_checkout( $fields ) {

    $fields['billing']['billing_city']['placeholder'] = 'Adaugati Localitatea';
    $fields['billing']['billing_city']['label'] = 'Localitate';
    return $fields;
}

The placeholders from both works... and is showing me the well words

and for remove the require - is work but it still show me the red star and i want to display that..

add_filter( 'woocommerce_billing_fields', 'wc_optional_billing_fields_camp', 20, 1 );
function wc_optional_billing_fields_camp( $fields ) {
    $fields['billing_postcode']['required'] = false;
    return $fields;
}

add_filter( 'gettext', 'customizing_checkout_text_shipping', 42, 3 );
function customizing_checkout_text_shipping( $translated_text_shipping, $untranslated_text_shipping, $domain )
{
    if ( $untranslated_text_shipping == 'Shipping' && is_checkout() ) {
