TOPIC: I don't see an add to cart button

Hello anyone, I recently started using quicksell 3.3.1, when generating codes for
buttons, I see various buy now buttons, even pay with paypal in an assortment of
styles but I don't see an add to cart, or a check button. Do these buttons even exist?
Some please help :~(

The user had the wrong package installed, it's all good now right?
