Activity data in "Course completion status" block not updating upon completion rollback

Steps to reproduce

• As a student, log in to a course in which:
  • A set of activities have been configured for manual self-completion
  • Course completion tracking has been configured and includes those activities
  • The "Course completion status" block has been added 
• Select several activities as complete
• Un-select those activities

Expected behavior

• Upon un-selecting the previously selected activities, the "Course completion status" block should no longer indicate those activities as being complete

Actual behavior

• The "Course completion status" block continues to indicated the un-selected activities as being complete

More details

• Behavior confirmed after cron ran again after de-selecting previously completed activities
• For a student, course-level completion status is accurate (e.g., if course status is "completed" and I then de-select some of the required activities as completed, the course status reverts to "pending")
• If I log in to the course as an instructor and override an activity completion, via the "Activity Completion" report:
  • As an instructor, the "course report" in the course completion status block does reflect updated completion data, and only the "x out of y" for required criteria is inaccurate
  • As a student, both the "x out of y" data and what is presented via the "more details" link remains inaccurate
