thx Joel,
this is my testing environment
https://staging.menabo.cpanel.regsm.it/biosphere/news-2/

I try with this function:

add_filter('wpc_terms_before_display', 'translate_acf_fields', 10, 2);

function translate_acf_fields($terms, $filter) {
    $fields_to_translate = array('tipologia', 'regione', 'cucina', 'origine', 'stagioni', 'informazioni', 'ingredienti', 'e_ora_di', 'Formaggio');
    if (function_exists('get_field_object') && in_array($filter['e_name'], $fields_to_translate)) {
        $newTerms = [];

        foreach ($terms as $k => $term) {
            $field_value = $term->name;

            if ($field_value !== false) {
                if (function_exists('icl_translate')) {
                    $current_language = apply_filters('wpml_current_language', NULL);
                    $field_value_translation = icl_translate('acf', $filter['e_name'], $field_value, $current_language);
                    $term->name = $field_value_translation;
                }
            }

            $newTerms[$k] = $term;
        }
        return $newTerms;
    }

    return $terms;
}

But filter is always in the first language (it), I hope you can help me.
THX
