Learn vocabulary - multiple choice is not working

i want to tests my linqs since few hours ago.
but this multiple choice which is the way that i prefer the most is not working…
it keep says No linqs selected…
i don’t know why…
could you solve this problem?

@aroxigas - It seems to be working for me. What do you see when you click the multiple choice button? Do you see the loading page? It can take a few seconds to load depending on your connection speed. Are you clicking on the button on the Vocabulary page or on the lesson page?
