Learner enrollments are always shown in the higher-order LOs (Learning Path or Certification). Therefore, to manage individual course completions, you need to operate within these higher-order structures.
Generally, learners enrolled in a course via a Learning Path or Certification are only shown in the 'Learners' section of the higher-order learning object (LO) and not at the course level. This means you need to manage their progress and completion within the context of the Learning Path or Certification.
