When a post is published or deleted, the counter will re-count all of your posts from each post type that exists.
An option value will be created/updated with the total number for each post type.
To display the option you can use a simple variable
$total_posts = get_option(‘total_post’, 0);
or the Voxel Dynamic Tags from Site > Option > Here you will add “total_{your-post-type-key}”
