Missing texts on the cookie buttons

Going to portableapps.com site I see the "standard" cookie confirmation request. If I choose Manage options, I can "somehow" (one or two checkboxes per option without explanation) edit my choices and I should confirm it somehow. But there are three ovals (micro-buttons) without any text only! White one, black and green. How the user should to know (without studying HTML source), what to choose?

BTW, I didn't find any contact / FAQ / forum ... about the portableapps.com site...
