Theme glitch with woocommerce

I am having an issue where the number of items you select on the product pages are showing up twice. The glitch is not a plugin issue but a theme issue with Highend. I tried switching themes and the issue went away. Is there a way to fix this? I really want to keep the theme but I don’t want the store to look like this. The store’s temp domain is http://justadropusa.wpengine.com/products/ and this is the page that if you select any product, the issue can be seen. See image also.

Note: the theme and WP are both up to date

Thank you!
