Calender doesn’t link to WooCommerce product

Dear Authors of the plugin,

i think this plugin is exactly what we are looking for. I testet the free version but for some reason when i create a product, exactly like it is shown in your documentation,
and link it to the calender in the pinpoint tab, it is not linked. + I want the add to woocommerce cart button and not the book now button. And i can’t remove the contact box.

Best Regards
Andre
