Remove automatically generated comments in course discussions

I installed CoursePress and created two new courses. I noticed that there are the same comments under each course. None of which was added under the actual course discussions. Therefore, there is zero comments from the courses for none was added yet. The comments seem to be generated from my blog posts. How do I remove these comments and prevent this from happening?

Also, is there a way to have comments under each individual unit instead of just the course level?

Thank you
