WooCommerce (Add To Cart Button) Missing HELP!

Hi everyone. I’m having trouble showing the Add to Cart Button for my sneaker selling website. I have figured out how to set sizes for my shoes, but when I select the size the add to cart button does not show! I’m using the latest version of WooCommerce and WP.

Website: https://www.limitedkicks.com

Also, If anyone knows how to fix the spacing on the Sneakers page. It seems so bunched up!

Thanks in advance!
