Gift cards not adding to cart - Refresh Theme

[BradgetDesigns]

Looking for some help regarding gift cards.  I know this worked previously but just noticed now that if I try to add a gift card to the cart, it just takes me to a cart with nothing in it.  

Now, if I check the "send as a gift" box and fill out the gift recipient information, it does add to the cart.  

I've checked the product page and anything else I can find searching around but this is just odd.  

Thanks in advance.
