An imported Fill-in-the-Blank quiz question from Blackboard 9.1 contents has an impeditive prefix "RESPONSE_" in the text for the possible answer. (Meanwhile, the multiple points fill in the blank question has no problem. A simple one-point Fill-in-the-Black quiz question only has this problem.)
It's in the way of our migration process from Bb to Canvas. I think that it's a bug of the importing quiz function from Bb, isn't it?
Everyone, were you having same troubles in your migrating process from Bb? Please let me know, if you have any solutions for this issue.
