"I downloaded the preset in one course (how/why did you do this?), deleted the preset in the Dataform activity (why did you do this?) , opened another course, added a new Dataform activity, uploaded and applied the preset."
I created a DataForm preset then tried to apply it to another DataForm and get all kinds of weird activity, like news forums from other courses showing in the course I was working on.
I there a video somewhere showing how to do this?
