I've uploaded a Woocommerce compatible theme to my site (www.edukal.webzenit.hu). On the cart page (in Hungarian "Kosár") there are 2 radio buttons denoting different shipping options. When either of those buttons is clicked, both disappear. I can get them back only by refreshing the page. Something must be wrong with my theme, because I checked other templates and this does not happen there. I don't see any option in elements regarding the "clicked" status of a radio button. Where should I look for the problem, how could I correct it? I'd appreciate any suggestions!
