Created Unassigned: Property Task.Enabled is not saved [11703]

I am using Microsoft.Win32.TaskScheduler.dll in an appliction to create and change a task. If I set the property Task.Enabled to False it will not be saved to Windows. All other information is saved properly.

Code:

Dim Task1 As Task = CurrentTaskService.RootFolder.RegisterTaskDefinition(PathOfTask, TaskDefinition1)
Task1.Enabled = False
Task1.RegisterChanges()

This was working properly in build 2.0.3, but does not work in build 2.2.0.
