x-term, check with my daughter (SilverMoonsong) about witches and hauntings and stuff like that. She may know about the Quizzyland Witch (she may BE the Quizzyland Witch for all I know.)
That's not it, however. I have to say 'apparently', 'cause I didn't code the thing, but 'apparently' the quiz-creator controller/editor robot was ordered to monitor for interrogatory words (who, what, when, where, why, how) and respond to those which are not completed with a ? with a stock response. It's also somewhat ignorant of many punctuation marks, since our robot has a minor stroke if you try to introduce /, &, %, @, or other ordinary stuff into questions.
Actually, it's good that it calls your attention to lack of question marks; it also points out when you fail to capitalize the beginning of a sentence. (It's only a young robot, born last fall. It'll get better as it matures.)
Your number 2 is odd. If you go back and place the question mark, it should cure the hiccup. Don't know why it doesn't. I think, though, that you can ignore the admonition and move ahead. Try it; let me know how you make out.
