I have tried to import grades from Google Classroom to the spreadsheet grade book. I have tried multiple times and for some reason the grade book is showing 3 columns of the same single assignment. Same grades, etc. I have checked the classroom and I only have one of these assignments of course. I'm not sure how to proceed. See image.
EDIT: And now it shows 4 times as I have tried to import the grades again. Usually things are overwritten. This week is the end of semester...terrible timing ;)
