How to get the Bump Button in Lesson work?

Hi All, I need to move a lesson plan. However, I tried the bump lesson button and it does not work.

Can anyone advise how to use this bump button? Is there any pre-requisite that I need to setup in order to get this bump button to work?

The screenshot below show that the bump was successful but the lesson was not moved. Please advise.

Hi @billngu, I wonder why the bump is not working. Is this class timetabled? The timetable is what Gibbon would use to determine what the “next” spot to bump it into would be. If you click on the “Year Overview” it should also show you all the available spots that it sees, if there are any. Hope this helps!
