Problem
The class type dropdown is empty.
Possible cause
Class types are loaded automatically when the page opens. If the list is empty, no class types may have been created in the system yet.
Solution
Reload the page and see if the class types appear.
Check whether class types have been created in the class type administration.
Create at least one class type if none have been created yet.
