[sims] Cannot Remove Student From Course

[CAM]

I have a student I am trying to remove from a course. I click delete in Course Manager, see that they are removed from Course Memberships and click Save. The student re-appears immediately after I click Save. It's driving me nuts and holding up my census, any ideas how to stop SIMS fooling around like this?

 

EDIT - SIMS reverts any changes I make to this student's course memberships, even setting core aims. What is it playing at???

 

EDIT EDIT - Super obscure solution found. Change the bugged membership's length to one day, save then delete. No idea what the cause was but it seems to be working normally now. One more for the Knowledgebase @PhilNeal!

Did you remove the student from the class that is linked to the course?

 

If not then adding an exception to the course will keep him out of trouble.

I had to remove them as they were on the same course for two different levels.

I have been founding this two as I had disabled auto update on the course as one class was doing 2 different BTECs. I found if you tick protect and save and then try deleting them they didn't come back.
