When going into NetClassroom to view the student schedules under classes, the Grid View defaults to the incorrect school. The issue continues when the correct school and Academic Year are selected as the session and term drop-downs are blank. Either selecting a different year and going back to the appropriate Academic Year or selecting the Homepage and going back to the Grid view will resolve this issue.
We resolved this issue in version 7.82.104, patch 19.
Download and install the latest patch, which contains all fixes from previous patches. If you are running an older version, download and install the latest version and then the patch.
Select a different year in the Year drop-down and go back to the current year. Or Select the Homepage and go back to Classes > Schedule > Grid View.
