Beans Breadcrumb on Custom Post Type

Hi Guys,

Don't know if anyone else has encountered this before, but I have added registered a custom post type and on the page the breadcrumb's link is displaying like this:

http://example.com/portfolio/example/0/

Adding a zero at the end... I've tried refreshing permalinks, but not sure what could be causing this.

Any help would be greatly appreciated.

Cheers,

Hayden

It is also worth mentioning that the url shouldn't be the full URL, the breadcrumb is dispalying like this Home / Portfolio / Example (the link is on portfolio so shouldn't be full url just http://example.com/portfolio/)

Here is the code used:

if ( ! function_exists('custom_post_type') ) {

// Register Custom Post Type
function custom_post_type() {

    $labels = array(
        'name'                  => 'Portfolio',
        'singular_name'         => 'Portfolio',
        'menu_name'             => 'Portfolio',
