Created Unassigned: TaskScheduler Version seems to be incorrect on Win2012R2 [11440]

When creating a new Showing the TaskEditor with an existing TaskDefinition the "Configure for:" shows an empty ComboBox.
The TaskDefinition Settings say it is Compatible with V2_2 but the TaskServer itself (remote Win2012R2) says HighestSupportedVersion V1. This only seems to be a problem when connecting remotely. I tried the TestClient localy on the server and everything looks fine.
