Unfortunately, the Get-SCJob SCVMM command was aliased to Get-Job , which is a command that comes with Windows / Powershell natively..
In order to get around this awesome (sarcasm) problem, if you are trying to get to the Windows jobs, you have to reference the fully qualified command, which is:
Microsoft.PowerShell.Core\Get-Job
Otherwise, you'll always get the results from Get-SCJob whether you intended to or not.
Have an open case on this, no hotfix / fix date supplied yet.
