Including a course into a certification appears to reset all of the activity completion data (but not course completion data) in the "Course Completion" report. The activities still contain the completion data (SCORM tracking, quiz attempts, etc.) but none of this appears in the "Course Completion" report, which is confusing our staff. Any activities completed after the course was included in the certification appear as normal.
Just as a reference point, none of the completions (before or after the course was included in the certification) are via the certification, because we've not started using certifications yet.
I guess the question is, is this expected behaviour? If so, it's a shame there's not a bit more warning about it (although this post may well act as warning enough). Additionally, is there any way to reverse this, so that the course completion report will correctly reflect when activities were completed?
