Underscore in Learner Response and Correct Response

Captivate courses are sending an underscore instead of a space between words in the Learner Response and Correct Response for quiz interaction results. The question text itself is fine. We use the Rustici SCORM Engine in our LMS to play SCORM courses. Courses are published to SCORM 2004 from Captivate 9. HTML 5/ responsive output was selected when publishing, but SWF output does the same thing. Courses built in Lectora do not have this problem.
