Duplicate Add To Cart Button. Brooklyn Theme. Add Quantity Correctly

[joshkdesign]

So there are two add to cart buttons on the individual product pages, the one at the top doesn't add the quantity to the cart (more than one) but the one at the bottom does, would like to switch these and make it just the one that is working properly. Can anyone help? Thanks!
