Why does metabox confuse sections when editing a post?

Question

WordPress

I select the necessary categories and add an entry, the metabox looks like this:

When I edit a post it looks like this:

it leaves only the selected categories, and all other categories are displayed down.

I create a taxonomy like this:

add_action( 'init', 'create_specialty_taxonomies' );
function create_specialty_taxonomies(){
    register_taxonomy('specialty', array('rating_applicants'), array(
        'hierarchical'  => true,
        'labels'        => array(
            'name'              => _x( 'Специальности', 'taxonomy general name' ),
            'singular_name'     => _x( 'Специальности', 'taxonomy singular name' ),
            'search_items'      =>  __( 'Поиск' ),
            'all_items'         => __( 'Cпециальности' ),
            'parent_item'       => __( 'Родительские' ),
            'parent_item_colon' => __( 'Родительские:' ),
            'edit_item'         => __( 'Редактировать' ),
            'update_item'       => __( 'Обновить' ),
            'add_new_item'      => __( 'Добавить новый' ),
            'new_item_name'     => __( 'Название новый' ),
            'menu_name'         => __( 'Специальности' ),
        ),
        'show_in_rest' => true,
        //'publicly_queryable' => 'publicly_queryable',
        'show_ui'       => true,
        'query_var'     => true,
        'rewrite'       => array( 
            'slug' => 'rating', 
            'with_front' => true, 
            'hierarchical' => true 
        ),
        'meta_box_cb' => 'post_categories_meta_box',
        'show_admin_column' => true,
        'show_in_quick_edit' => true,
        'sort'          => true,
        '_builtin'      => true,
    ));
