Products are not adding to the cart

I had posted this yesterday but it was at the end of a bunch of recent problems with the new update. I need to get this looked at right away. I have opened access for support to look at yesterday.

Book product page doesn't add to the cart but rather takes the customer to an entirely different product. It happens to several and I have had to recreate the product page. I don't want to keep doing this as it time I don't have to spend recreating a store that is already set up. Can someone please tell me what is going on with this and how it can be fixed without having to recreate product pages?
