Hi @andry79fi,

Can you please try using the below custom code to add custom fields in the order info section per your requirements and see if it works as expected? You will need to adjust the changes in the code as per your requirements.

function custom_order_info_fields( $fields, $order ) {
    // Add your custom meta fields here
    $custom_fields = array(
        array(
            'label' => 'ID:',
            'value' => $order->get_meta('_billing_tckimlik_vergino', true),
        ),
    );
       
    // Merge the custom fields with the existing fields
    $fields = array_merge( $fields, $custom_fields );
    return $fields;
}
add_filter( 'wcdn_order_info_fields', 'custom_order_info_fields', 10, 2 );
