404 on only one taxonomy

Hi,

I currently have 3 different taxonomies for one of my CPT and two of them work fine, but one them always shows a 404 no matter what! I’ve tried changing the slug, updating permalinks, etc and it still doesn’t work. Below is what I’m using to register it:

$labels = array(
		'name'              => _x( 'Category', 'taxonomy general name' ),
		'singular_name'     => _x( 'Category', 'taxonomy singular name' ),
		'search_items'      => __( 'Search Categories' ),
		'all_items'         => __( 'All Categories' ),
		'parent_item'       => __( 'Parent Category' ),
		'parent_item_colon' => __( 'Parent Category:' ),
		'edit_item'         => __( 'Edit Category' ),
		'update_item'       => __( 'Update Category' ),
		'add_new_item'      => __( 'Add New Category' ),
		'new_item_name'     => __( 'New Category' ),
		'menu_name'         => __( 'Category' ),
	);

	$args = array(
		'hierarchical'      => true,
		'labels'            => $labels,
		'show_ui'           => true,
		'show_admin_column' => true,
		'query_var'         => true,
		'rewrite'           => array( 'slug' => 'type' ),
	);

	register_taxonomy( 'cs_category', array( 'case_studies' ), $args );

Any ideas?

I can send you a URL privately if needed.
