University - Choosing Your Next Enrollment and other bugs

Problems like this one are very easy to fix. Just go back to the main menu without saving, then reload the current save and try again.

You can even use that method to refresh your memory of the household's aspirations and skills. Load the save and the household, cancel their enrollment, check their aspirations and skills, then go back to the main menu without saving. Reload the save and the household, and they should be asking to re-enroll again.
