I have three sections of the same course. I have a Master Shell that I update, and then I share that Master to the Commons. I then import from the Commons in to my course shells. Each time I do this, all of the old material is duplicated, not replaced. I end up with two copies of everything except the new stuff I added with the Master-to-Commons update.
Is this the expected behavior?
I there any way an exported Updated Shared Master can be imported into an existing Course without duplicating all the old material?
