When sheets are created for each selected Google Classroom course, the name of the sheet is limited to 50 characters. Many times, when Google Classroom courses are auto generated by an institution, their names will exceed 50 characters. Courses that have more than 50 characters are still usable, however, the course name will cut at 50 characters. This may result in some identifying information in the course name being missing. To circumvent this issue, you can try renaming your Google Classroom course or contacting your administrator to see about shortening the name(s).
