I just answer to myself. I found out the pb is about localization. My wp was in french and changing for english solved the issue.

For those who are trying to find a solution, it seems that by just adding the translated version of $meta_boxes it is working.

In the file admin-user-profile-fields.php, change :

var meta_boxes = ['<?php echo implode("', '", $meta_boxes); ?>'];

to

      <?php 
        $translated_metaboxes = array();
        foreach ($meta_boxes as $meta_box) {
          $translated_metaboxes[] = __($meta_box);
        }
       ?>

      var meta_boxes = ['<?php echo implode("', '", $translated_metaboxes); ?>'];
