Course or schedule does not look right

No Schedule Lessons action: add lessons first, select a learner who still has unscheduled work, or check whether that learner’s course is already fully scheduled.
No empty-week scheduling prompt: the week must be current or future, contain an instructional date, have no scheduled lessons, and have unscheduled learner-course work available.
Lessons appear on unexpected days: review the course weekdays and School Year Setup exceptions.
Alternating Weeks is hidden: the course must be fully scheduled on exactly five weekdays at one lesson per day with future planned work.
A move skips a date: planned breaks and regular non-learning days are intentionally skipped for remaining lessons.
Lesson text is wrong: select the planner lesson card and use Edit lesson for a small correction.
The whole outline is wrong: use the double-confirmed Reset course lessons action from Edit Course, then rebuild or import again.
