Product Variant not Showing on Product Page (Brooklyn Theme)

Hi, 

On my Giftcard Product Page, the variants are not showing. How can I solve this?

The variant picker block is not showing on my default product page?

Still not working. On a featured product section on the homepage the variants are showing, but then on the product page they are not.
