Hi! Two teachers occasionally created the course with the same name but with different lessons inside. Let it be Course1 and Course2. I want to merge these courses into one. Editing the lesson I changed "other group" from Course2 to Course1 and saved. The breadcrump changed correctly to Course1. But in the left sidebar I still see Course2. And when I go to Course1, I can't see this lesson. I tried cache cleaning - it didn't help. Opigno verseion - 1.16. How to change Lesson's course correctly?
