In my one course (out of 6) the grade book is not showing the quarters, only the entire course. I went into Canvas Guides, read "How do I use grading periods in a course?" tried all three locations they suggested (Assignment List, Grade Book and Student Grades). The pictures on the help page do not look like my Assignment List, Grade Book or Student Grades. They don't look like any of my courses. So, obviously I must not have access to something although I have been teaching and writing Canvas courses for at least 10 year. So, if I have 5 courses showing quarters, how do I get this 6th one too? Thanks for suggestions.
