Result different from the live demo

Hello there! I notice that upon installing this plugin, the result is different from the live demo. It totally acts differently. Besides, the box overlays the price, product name, and the ‘add to card’ button. I tried to uninstall it but it did not revert back to its previous layout. Somebody please help me. Here is the website I’m currently working with. Thank you.
