Duplicate children VM's listed

I am having an problem where when I load a vAppTemplate and look at the children (GetChildren) I see two of every VM.

Quick example:

VappTemplate has 3 VM's in it.  ServerA, ServerB, ServerC

foreach (VappTemplate vm in template.GetChildren())
{

  Console.WriteLine(vm.Reference.name);
}

Output:

ServerA

ServerB

ServerC

ServerA

ServerB

ServerC

Looking at the of returned Vm's in detail - they are copies.  I am getting two back.

Ideas?  Or is this a SDK bug?

(1.5 SDK on VCD 1.5)
