A copy of the Woocommerce Cart on another page is not showing the correct prices. How can I fix this?

Question

We created an additional page on our webshop for some kind of 'quotation'. On that page we'd like to load the cart. The contents of the 'quotation' is basically the same as the cart content.

We tried copying all of the WooCommerce code from the template file cart.php.

Everything is showing correctly, except for the prices. Our quotation cart is showing the basic prices that are set up in the WooCommerce back-end.

But here's our problem: When adding a product to the cart, there are additional price settings which we custom coded by using some hooks, like cart item data that's being added.

All of our custom code works perfectly fine when opening the regular WooCommerce cart, but when showing that exact Cart on another page, prices are 'reset' to the regular starting prices.

The reason we copied the code from the cart.php template file is the ability to change the structure with additional css/html.

Here you can find the shortcode & complete function of our 'quotation' cart:
