Hide one name of group field

Hello,

I have edited pdb-single-river.php and use the shortcode [pdb_single template=”river”] to display datas. I’d like to hide the group field title called “votre inscription” name :”personal”
https://joggingclublicquois.fr/inscription/single-fiche/?pdb=23

I don’t know how to do that

Here is my file pdb-single-river.php

<?php
/*
 * default template for displaying a single record
 *
 * this is the new "WordPress style" template
 *
 * each group with the "visible" attribute checked will display its fields in the order set
 * in the manage database fields page.
 *
 * if there are specific fields you wish to exclude from display, you can include the "name" value of
 * the field in the $exclude array like this: $exclude = array( 'city','state','country' ); or whatever
 * you want. Leave it empty (like it is here) if you don't want to exclude any fields.
 *
 * this template is a simple demonstration of what is possible
 *
 * for those unfamiliar with PHP, just remember that something like <?php echo $group->name ?> just prints out
 * the group name. You can move it around, but leave all the parts between the <> brackets as they are.
 *
 */

// define an array of fields to exclude here
$exclude = array('mailing','phone','country','address','zip','email','suppression');

?>

<div class="wrap <?php echo $this->wrap_class ?>">

  <?php while ( $this->have_groups() ) : $this->the_group(); ?>

  <div class="section" id="<?php echo Participants_Db::$prefix.$this->group->name ?>">

    <?php $this->group->print_title( '<h2>', '</h2>' ) ?>

    <?php $this->group->print_description( '<p>', '</p>' ) ?>

      <?php while ( $this->have_fields() ) : $this->the_field();

          // skip any field found in the exclude array
          if ( in_array( $this->field->name, $exclude ) ) continue;

          // CSS class for empty fields
					$empty_class = $this->get_empty_class( $this->field );

      ?>

    <dl class="<?php echo Participants_Db::$prefix.$this->field->name.' '.$this->field->form_element.' '.$empty_class?>">

      <dt class="<?php echo $this->field->name.' '.$empty_class?>"><?php $this->field->print_label() ?></dt>

      <dd class="<?php echo $this->field->name.' '.$empty_class?>"><?php $this->field->print_value() ?></dd>

    </dl>

    	<?php endwhile; // end of the fields loop ?>

  </div>

  <?php endwhile; // end of the groups loop ?>

</div>

Thanks for your help
