custom post type dash in permalink

Hi, when I use dashes “word-secondword-thirdword” in custom post type permalink, I get 404 (of course after refreshing permalink structure via settings / permalinks in the wp admin)

when I remove the dashes “wordsecondwordthirdword” , no error, articles get online good. any idea why ?

second bonus question : how do I put the year in the custom post type structure ?

register code : `
function poleouest_article() {
$labels = array(
‘name’ => ‘poleouestarticle’,
‘singular_name’ => ‘Article’,
‘add_new’ => ‘Add Article’,
‘add_new_item’ => ‘Add New Article’,
‘edit_item’ => ‘Edit Article’,
‘new_item’ => ‘New Article’,
‘all_items’ => ‘All Articles’,
‘view_item’ => ‘View Article’,
‘search_items’ => ‘Search Articles’,
‘not_found’ => ‘No Articles found’,
‘not_found_in_trash’ => ‘No Articles found in Trash’,
‘parent_item_colon’ => ”,
‘menu_name’ => ‘Photo News’
);

$args = array(
‘labels’ => $labels,
‘public’ => true,
‘publicly_queryable’ => true,
‘show_ui’ => true,
‘show_in_menu’ => true,
‘query_var’ => true,
‘rewrite’ => array( ‘slug’ => ‘photobretagnenews’ ),

‘has_archive’ => true,
‘hierarchical’ => false,

‘supports’ => array( ‘title’, ‘editor’, ‘author’, ‘thumbnail’, ‘excerpt’, ‘comments’ )
);

register_post_type( ‘poleouestarticle’, $args );
}
add_action( ‘init’, ‘poleouest_article’ );`
