Yes, I am not messing with the default tasks. Only trying to add back the Scheduled task I had in my policies, before it went haywire on last update. I open/edit an existing policy, go to Settings, Tools, expand Scheduler, click Edit, Add, choose the option from drop down "On-demand computer scan", and Task name remains greyed out, and says "Automatic update after dial-up connection" under task name, and you cannot change it.
