Hello,
When you copy a activity on a course the copied activity has the identical name compared to the original one.
This is very misleading and confusing to a normal user, the copied activity name should have some suffix f.ex biology_copy1
at the moment wheny ou copy biology named activity second biology named activity is made on the course below it.
