Multiple Bookings Not showing up in Cart

When a booking multiple products for the same days the products DO NOT show up in the cart. The cart icon in navigation shows (3) but in the cart there is only one product with no “quantity” itentifier.

For example: If I want to rent 2 bikes for me and my wife. I book 2 bikes for the same amount of time on the same days. The price goes up, the number on the cart goes up, but when you click to look in the actual cart there is only one “booking” listing and the quantity field says “1 Day(s)” which is not quantity.
