Comment Form title reply to

Hi guys, here i am i modified quite full of the comment wordpress basic form and i’ve got a problem, i don’t find the solution on the forum and even not on google then i posted here.

My issue is that my ‘title-reply’ don’t change to ‘title-reply-to’ When i try to repply to another comment.

Here is my comment-form function :

$args = array(
	'fields' => apply_filters(
		'comment_form_default_fields', array(
			'author' =>'<p class="comment-form-author">' . '<input id="author" placeholder="Votre nom complet ici..." name="author" type="text" value="' .
				esc_attr( $commenter['comment_author'] ) . '" size="30"' . $aria_req . ' />'.
				'<label for="author">' . __( 'Nom' ) . '</label> ' .
				( $req ? '<span class="required">(Obligatoire)</span>' : '' )  . '</p>' ,

			'email'  => '<p class="comment-form-email">' . '<input id="email" placeholder="[email protected]" name="email" type="text" value="' . esc_attr(  $commenter['comment_author_email'] ) .
				'" size="30"' . $aria_req . ' />'  .
				'<label for="email">' . __( 'Email' ) . '</label> ' .
				( $req ? '<span class="required">(Obligatoire)</span>' : '' ) . '</p>'
		)
	),

	'label_submit'      => __( 'Envoyer vos condoléances' ),
	'comment_field' => '<p class="comment-form-comment">' .
		'<label for="comment">' . __( 'Vos condoléances :' ) . '</label>' .
		'<textarea id="comment" name="comment" cols="45" rows="8" aria-required="true"></textarea>' .
		'</p>',

    'comment_notes_after' => '',

    'title_reply'       => __( 'Laissez vos condoléances' ),

    'title_reply_to'    => __( 'Répondre à %s' ),

    'comment_notes_before' => '<p class="comment-notes">' .
    __( 'Votre adresse email ne sera pas publiée.' ) . ( $req ? $required_text : '' ) .
    '</p>'
);

	comment_form($args, $post_id); ?>

Thx in advance for repplies…. Hoppefully someone’ll find a solution
