Just found out that

1. Enrollment Date for students in classes must be the class start and end date. Put this in your trainings, it is not currently in your trainings and it has a huge impact on the class functionality.

2. Section ID cannot contain alpha-characters, it has to be numeric. I cannot fix the issue in number one above VIA import due to this. Either fix this to allow alpha-characters for Section ID's or don't let us use alpha-characters for section ID's. I specifically asked if I could make them alpha-characters and now I'm left high and dry trying to fix this.
