ESS Timesheet default view

We are implementing ESS time entry. We have created some custom views in the portal but are having difficulties deleting them.

We select the timesheet view and select the Properties.  We remove the checkbox for Initial View.  When we delete the View, we get the following messages:

"ESS TimeSheet" view still exists as Cross-User View

"ESS TimeSheet" view deleted.

But the view is not deleted.  How to I change this view to a non Cross-user view? 

We would actually like to delete ALL custom views that have been created.

Thanks.
