breadcrumbs not showing starting-point "Shop"

Hi there 🙂

In the breadcrumbs is only showed the “Home”-Link but not the starting-point of the shop itself.

I display 3 categories on http://www.stardessert.ch/angebot/shop and after one of the 3 categories got selected, all the customer sees in the breadcrumbs is “Startseite / category” and not “Startseite / Shop / category” as it should be.

I used this Code:
function my_woo_custom_breadcrumb_home_url() {
return ‘http://www.stardessert.ch/angebot/shop’;
}

add_filter( ‘woocommerce_breadcrumb_defaults’, ‘jk_change_breadcrumb_home_text’ );
function jk_change_breadcrumb_home_text( $defaults ) {
// Change the breadcrumb home text from ‘Home’ to ‘Shop’
$defaults[‘home’] = ‘Shop’;
return $defaults;
}

I’d appreciate any hint to solve it.
Thank you
