EDR 4.6
EDR is unable to recognize the user account used to create the report. This could happen if the user account was created with the role of 'user' or even 'controller' first and then changed at a later date to 'admin.'
Option 1: Create a new schedule using a user that has always existed with the 'admin' role
Option 2: Reboot the EDR appliance.
