Hi azin Izadifar , thanks for getting in touch! The course 'EDIT' options are visible in the courses that you have created, you can see this option on the left hand side of the navigation menu. These are only visible to course administrators and not the learners (Course Setup, Administer Learners, Credentials etc - as per screenshot)

Please refer to our Course Creator Guide here which has extensive documentation to help you get started.
