Enrolment not working

I’m trying to reenroll at uwa after semester at curtin. When enrolling, for unit sets it says.

Code. Status. Action

MJD-EMINE Unconfirm. Confirm

MJD-EMINE. Ended. Reinstate

And when I press either of the actions it just says record updated successfully and nothing changes. Then when I try to enroll in units it says.

Please enrol in a degree specific major for each undergraduate degree before enrolling in any units. Not that you can only have one degree specific major per award.

Anyone know what’s going on?
