error layout cart page

I am testing the purchased plugin.
I have created a test product and everything works fine.
I add the product to the cart and everything works fine, but if I see it from the mobile the cart busts the whole layout when it contains a BOPO product.
here is the example: https://www.sanitarbaby.com/prodotto/tetstttt/
Add it to your cart and see the mobile cart.
How can I solve?
Do I have to rewrite all the CSS?
Thank you
