Teachers may notice upon opening their Gradebook that grades entered previously are no longer there.
Gradebook grades are entered and automatically saved in the system. Sometimes, these grades can accidentally be overwritten if multiple windows are open. Make sure the teacher or admin entering grades does not have another Gradebook window open or it may overwrite the data the user entered in the Gradebook. This is common when a teacher has multiple browser windows open to enter and review grades for students.
