Product Category Meta Description Template not working

I’m trying to set a meta description template for our product categories, but it doesn’t seem to be working.
It keeps defaulting to using the product template meta description instead.

Now I did add in some code that I found in another support repsonse to the functions file in order to get our Product meta description templates to function but it appears that it’s overriding everything else.

Any ideas?

Code attached below:

add_action( 'rank_math/frontend/description', function( $description ) {
	global $post;
	$desc = RankMath\Post::get_meta( 'description', $post->ID );

	if ( ! $desc ) {
		$desc = RankMath\Helper::get_settings( "titles.pt_{$post->post_type}_description" );
		if ( $desc ) {
			return RankMath\Helper::replace_vars( $desc, $post );
		}
	}

	return $description;
});
