Gift card’s product page display is Disrupted

Hi everone. I’ve tries using the free version of this plugin, but the product page it’s generates for the gift card, is seriouslly visioally Disrupted.
Even when I create a fresh product tamplate just for this product, it Disruptes the dicplay.
It’s also very heavy pn the php, from so reason.
I did not give a link to the page, beacuse I preffer not to activate it until it’s resolved.
