Sometimes this happens because a student is enrolled in multiple sections of the same course.
To correct this:
  1. From the menu in the upper left select Academics
  2. Navigate to Scheduling > Requests and Schedules> Manage Enrollment
  3. Use the Filters to locate the Student and click Find
  4. Click View to the right of the Student's name
  5. Click on Drop to the right of the extra section and choose the reason as Change Sections.
Once this is done - check the credits. If this does not work,try to re-trigger the credits.
