Help with World Showcase Quests

Hi all! I haven't played in about 2 years but I'm back and I'm super excited to do the WSC quests. I'm stuck on the Mexico quest though. I'm on question 4 "What is the name of the people who lived in Chichen Itza?" and I *think* the answer is the Mayan people but I can't get it to take. I've tried Maya, Mayan, Mayan people, etc. and nothing works. Am I dumb and just missing the actual answer?

I also tried to quit the quest and it just wont.

Not sure if this is a me problem or a bug, but either way I appreciate the help!
