I have experienced a problem with course overview for lesson activities.
When the lesson activity has no questions page, no matter the completion setting the course overview block still shows the active open, whether delayed or future.
I experimented with different combinations of settings, such as practice lesson, no note, complete by preview, to reach the end of the lesson, etc. Only when there is a page of questions in the lesson that the course overview block computes the completion data.
Has anyone had this same problem? I use Moodle 3.3.2+
