How do I remove the flashing dashboard alert for incomplete portal attendance?

If you are using the Attendance feature in the Staff Portal this alert will fall off the Executive Dashboard when the portal attendance for the classes has been completed. 

If you are not using the Attendance feature and would like to remove that alert go to the Staff (menu) > Staff Portal > Portal Settings. In the Features section remove the check mark next to Attendance and Save Changes

Note: With this change you will no longer be able to take attendance in the Staff Portal.
