I have multiple knowledge checks in my material. I just transitioned the material from SL 2 to SL 3 and when I preview my knowledge checks, not all of the answer(s) identified as being correct in the knowledge checks are "registering" - I can't even select all of the correct answers, so when I 'Submit' I get the 'Incorrect' layer every time, i.e. I can't get past the first knowledge check. Also, the knowledge check doesn't allow one to select a wrong answer from the options offered. Like it is self grading.
