How to Remove a Language Course

Does anyone know how to remove a language course? I selected one by accident, but all I can seem to do from the Lingvist website is archive the course, but not delete it. Can someone tell me how to delete a course completely? The course in question is German from English.

Archive is the only option [1] [2] Basically, Lingvist doesn't care if you have added extra language that you don't practice, why do you care?
