How can I unenroll/delete a student from my course?

[SFG315]

As the teacher, I want to make sure I can unenroll/delete students from the course, but when I go to delete a student (having enrolled myself as one to test) it says I do not have permission to do this. Is this because I'm using myself? I need to make sure I can remove students because I'm using this at a high school where students transfer in and out of classes often.

You go to People on the left-hand side and you will have the option of deleting each user,
