Product category title, product tags and descriptions not showing

Hi there,

I am using the free version of the Neve theme for Woocommerce, the product category page titles, product tags page titles, and descriptions are not showing up on the pages.

I have searched high and low and only found the solution for the product category page titles, and description by Poonam Namdev (@poonam9) which is,

add_action( 'woocommerce_archive_description', 'woocommerce_taxonomy_archive_description', 100 );
function woocommerce_taxonomy_archive_description() {
if ( is_product_category()) {
	$cat_title = single_tag_title("", false);
	echo '<h1>' . $cat_title . '</h1>';
$cat_desc = term_description( $cat_id, 'product_cat' );
echo $cat_desc;
}
}

I am using product tags for my brands, I have the breadcrumbs at the top of the page but no product tags page titles, or descriptions.

Is there any code I could add to make them show??
Thanks so much.
