Custom Post Type with Category Separate

I have create two custom post type(movie type1 , movie 2) from function.php, but when make new category, this category duplicates itself in the POSTS(Article) and other CPT(movie type1, movie2) why?

enter image description here

function custom_post_type_week() {           // Set UI labels for Custom Post Type         $  labels = array(             'name'                => _x( 'Movie type 1', 'Post Type General Name', 'twentythirteen' ),             'singular_name'       => _x( 'Movie type 1', 'Post Type Singular Name', 'twentythirteen' ),             'menu_name'           => __( 'movie type 1', 'twentythirteen' ),             'parent_item_colon'   => __( 'Parent Movie', 'twentythirteen' ),             'all_items'           => __( 'All Movies', 'twentythirteen' ),             'view_item'           => __( 'View Movie', 'twentythirteen' ),             'add_new_item'        => __( 'Add New Movie', 'twentythirteen' ),             'add_new'             => __( 'Add New', 'twentythirteen' ),             'edit_item'           => __( 'Edit Movie', 'twentythirteen' ),             'update_item'         => __( 'Update Movie', 'twentythirteen' ),             'search_items'        => __( 'Search Movie', 'twentythirteen' ),             'not_found'           => __( 'Not Found', 'twentythirteen' ),             'not_found_in_trash'  => __( 'Not found in Trash', 'twentythirteen' ),         );            $  args = array(         'label'               => __( 'movies', 'twentythirteen' ),         'description'         => __( 'Movie news and reviews', 'twentythirteen' ),         'labels'              => $  labels,         'supports'            => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'comments', 'revisions', 'custom-fields', ),         'hierarchical'        => true,         'public'              => true,         'show_ui'             => true,         'show_in_menu'        => true,         'show_in_nav_menus'   => true,         'show_in_admin_bar'   => true,         'menu_position'       => 5,         'can_export'          => true,         'has_archive'         => true,         'exclude_from_search' => false,         'publicly_queryable'  => true,         'capability_type'     => 'page',         'show_in_rest'        => true,                   // This is where we add taxonomies to our CPT         'taxonomies'          => array( 'category','post_tag' ),     );              register_post_type( 'movies', $  args );   }     add_action( 'init', 'custom_post_type_week', 0 );
