I’m sorry, it seems I misunderstood.
Thank you very much for your answer.
Thank you for your reply.
When I first started editing,
the “Lesson Complete” button was displayed when the lesson was completed,
and the “Completed” and “Next Lesson” buttons were displayed while the lesson was in progress.
Currently, the “Lesson Complete” button is displayed while the lesson is in progress,
and the “Completed” and “Next Lesson” buttons are displayed when the lesson is completed.
Is this the correct behavior?
