The React component CourseCreator had hard-coded labels various input fields : https://github.com/WikiEducationFoundation/WikiEduDashboard/blob/master/app/assets/javascripts/components/course_creator/course_creator.cjsx

Instead, it should use the I18n javascript to utilize translated strings, like the StudentList component does: https://github.com/WikiEducationFoundation/WikiEduDashboard/blob/master/app/assets/javascripts/components/students/student_list.cjsx
