(Just in case anyone can't tell, I think that the problem is that the year of the games is not specified. I think the questions came from the Global Challenge.)
Have you played the quiz they were from or at least checked it? If the question was altered, it takes a while for the change to be made in the database and so it might not specify the year in GC while in the quiz it might in each question.
If you have, did you send a correction note? Otherwise it will never get fixed. Even if the quiz writer has left the site, and editor will take care of it.
