Woocommerce custom fields: some values are not in the order page

I am not a developer but somehow managed to add Woocommerce custom fields to checkout and order edit pages. There are similar questions, but I can't find the correct solution.

Some custom fields are visible in the admin order edit page but they don't display the values and are not added to order emails.

What am I missing?

Please see screenshot at the end.

<?php

/**
 * DOMAINE 
 */


    /**
     * Add the field to the checkout
     */
    add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field_domaine' );

    function my_custom_checkout_field_domaine( $checkout ) {

        echo '<div id="my_custom_checkout_field"><h3>' . __('Votre question') . '</h3>';

        woocommerce_form_field( 'domaine', array(
            'type'          => 'select',
            'class'         => array('domaine form-row-wide'),
            'label'         => __('Dans quel domaine se situe votre question ?'),
            'required'    => true,
            'options'     => array(
                            'famille' => __('Famille'),
                            'immobilier' => __('Immobilier'),
                            'vie_pro' => __('Vie professionnelle'),

First and foremost, there is no need to use the same hook over and over for each additional field

Here and there you also have typos, uppercase where you otherwise use a lowercase letter or a different name

/**
 * Add fields to the checkout
 */
function my_custom_checkout_fields( $checkout ) {

    // domaine
    woocommerce_form_field( 'domaine', array(
        'type'          => 'select',
        'class'         => array('domaine form-row-wide'),
        'label'         => __('Dans quel domaine se situe votre question ?'),
        'required'    => true,
        'options'     => array(
            'famille' => __('Famille'),
            'immobilier' => __('Immobilier'),
            'vie_pro' => __('Vie professionnelle'),
            'fiscalité' => __('Fiscalité'),
            'droit_des_societes' => __('Droit des sociétés'),
            'autre' => __('Autre')
        ),
        'default' => 'famille'
    ), $checkout->get_value( 'domaine' ));

    // question
    woocommerce_form_field( 'question', array(
        'type'          => 'textarea',
        'class'         => array('my-field-class form-row-wide'),
        'required'    => true,
        'label'         => __('Merci de décrire le plus précisément possible votre demande et vos questions'),

    ), $checkout->get_value( 'question' ));

    // recherches
    woocommerce_form_field( 'recherches', array(

        'class'         => array('recherche-field form-row-wide'),
        'label'         => __('Avez-vous déjà effectué des recherches ?'),
        'required'    => true,

}
add_action( 'woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta_domaine', 10, 1 );

Additional: To avoid adding an if statement every time, you can use a foreach loop instead

So this

/**
 * Update the order meta with field value
 */
function my_custom_checkout_field_update_order_meta_domaine( $order_id ) {
    if ( ! empty( $_POST['domaine'] ) ) {
        update_post_meta( $order_id, 'domaine', sanitize_text_field( $_POST['domaine'] ) );
    }
    
    if ( ! empty( $_POST['question'] ) ) {
        update_post_meta( $order_id, 'question', sanitize_text_field( $_POST['question'] ) );
    }
    
    if ( ! empty( $_POST['recherches'] ) ) {
        update_post_meta( $order_id, 'recherches', sanitize_text_field( $_POST['recherches'] ) );
    }
    
    if ( ! empty( $_POST['professionnel'] ) ) {
        update_post_meta( $order_id, 'professionnel', sanitize_text_field( $_POST['professionnel'] ) );
    }
    
    if ( ! empty( $_POST['statut'] ) ) {
        update_post_meta( $order_id, 'statut', sanitize_text_field( $_POST['statut'] ) );
    }
}
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta_domaine', 10, 1 );

Is therefore also possible in this way

/**
 * Update the order meta with field value
 */
function my_custom_checkout_field_update_order_meta_domaine( $order_id ) {
    // Add fields
    $fields = array('domaine', 'question', 'recherches', 'professionnel', 'statut');
    
    // Loop
    foreach ( $fields as $field ) {
        $field_post = $_POST[$field];
        if ( ! empty( $field_post ) ) {
            update_post_meta( $order_id, $field, sanitize_text_field( $field_post ) );
        }
    }
}
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta_domaine', 10, 1 );
