I have come across what I believe is an issue with this plugin. When I go to create slots and it requires the mandatory Teacher field, the drop-down menu only lists those staff who have the "Teacher" role in the course.
As I manage the subject/course, my role was Manager (we call it Site coordinator), and I was unable to add time slots for myself. I have solved this by demoting myself to Teacher (we had two Managers in my particular example) and now I can use it perfectly - my name appears in the drop down menu, and I can add slots for myself.
Some courses will only have one Manager, and so this won't always be possible. Is it feasible to request that staff with the role of Manager be included when populating the drop-down menu?
