Custom Single Post for post type

Hello every one,
I have a strange problem with my Custom Single Post for post type “single-park_auto.php”, I’m working in a child theme and i use this code generated with “Custom Post Type UI” :

function cptui_register_my_cpts_park_auto() {

	/**
	 * Post Type: Park auto.
	 */

	$labels = array(
		"name" => __( "Park auto", "custom-post-type-ui" ),
		"singular_name" => __( "Park auto", "custom-post-type-ui" ),
		"menu_name" => __( "Park auto", "custom-post-type-ui" ),
		"add_new" => __( "Ajouter une voiture", "custom-post-type-ui" ),
		"add_new_item" => __( "Ajouter une nouvelle voiture dans le Park Auto", "custom-post-type-ui" ),
		"edit" => __( "Modifier", "custom-post-type-ui" ),
		"edit_item" => __( "Modifier Park auto", "custom-post-type-ui" ),
		"new_item" => __( "Nouveau voiture", "custom-post-type-ui" ),
		"view" => __( "Aperçu", "custom-post-type-ui" ),
		"view_item" => __( "Voire la voiture", "custom-post-type-ui" ),
		"search_items" => __( "Cherche une voiture", "custom-post-type-ui" ),
		"not_found" => __( "voiture introuvable", "custom-post-type-ui" ),
		"not_found_in_trash" => __( "Voiture introuvable dans la Corbeille", "custom-post-type-ui" ),
	);

	$args = array(
		"label" => __( "Park auto", "custom-post-type-ui" ),
		"labels" => $labels,
		"description" => "Ajouter ou modifier les voitures de votre park automobile",
		"public" => true,
		"publicly_queryable" => false,
		"show_ui" => true,
		"delete_with_user" => false,
		"show_in_rest" => false,
		"rest_base" => "",
		"rest_controller_class" => "WP_REST_Posts_Controller",
		"has_archive" => false,
		"show_in_menu" => true,
		"show_in_nav_menus" => true,
		"exclude_from_search" => false,
		"capability_type" => "post",
		"map_meta_cap" => true,
		"hierarchical" => false,
		"rewrite" => array( "slug" => "park_auto", "with_front" => true ),
		"query_var" => true,
		"menu_position" => 5,
		"menu_icon" => "dashicons-cart",
		"supports" => array( "title", "thumbnail" ),
		"taxonomies" => array( "post_tag" ),
	);

	register_post_type( "park_auto", $args );
}

add_action( 'init', 'cptui_register_my_cpts_park_auto' );

Inside the home page i have this code :

<?php query_posts('post_type=park_auto'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
	<div id="desc-cars-home">
		<h2><a href="<?php the_permalink() ?>"><?php the_field ('classe');?> <?php the_field ('marque_et_model');?></a></h2>
	</div>
<?php endwhile; else : ?>
<?php endif; 
wp_reset_query();
?>

So every time i click the link it redirect me to the some index or single.php , not to the page of product “single-park_auto.php”

Have any one understand this issue?

Thanks a lot.
