VBA, copy sheet models don't include elements for all copies

Hi

As a part of a bigger VBA-project I'm having trouble with this part. I want a copy a sheet model a couple of times. But the elements included in my sourcemodel are only included in the first copy. All following sheet models are completely empty. 

Sourcemodel looks like this:

Second and third copy looks like this: 

Here's my code:

Sub testCopyModels()
    Dim sheetTemplate As ModelReference
    Dim CreateNewModel As ModelReference
    Dim inputModelToCopy As String
    inputModelToCopy = "K-20-1-0101"
    Set sheetTemplate = ActiveDesignFile.Models(inputModelToCopy)
    Set CreateNewModel = ActiveDesignFile.Models.copy(sheetTemplate, "K-20-1-0103")
    Set CreateNewModel = ActiveDesignFile.Models.copy(sheetTemplate, "K-20-1-0104")
    Set CreateNewModel = ActiveDesignFile.Models.copy(sheetTemplate, "K-20-1-0105")

End Sub

I noticed that if I add some command in between everything works as expected:

Sub testCopyModels()
    Dim sheetTemplate As ModelReference
    Dim CreateNewModel As ModelReference
    Dim inputModelToCopy As String
    inputModelToCopy = "K-20-1-0101"
    Set sheetTemplate = ActiveDesignFile.Models(inputModelToCopy)
    Set CreateNewModel = ActiveDesignFile.Models.copy(sheetTemplate, "K-20-1-0103")
    CadInputQueue.SendKeyin ("place smartline; xy=0,0;xy=100,100")
    Set CreateNewModel = ActiveDesignFile.Models.copy(sheetTemplate, "K-20-1-0104")
    CadInputQueue.SendKeyin ("place smartline; xy=0,0;xy=100,100")
    Set CreateNewModel = ActiveDesignFile.Models.copy(sheetTemplate, "K-20-1-0105")
    CadInputQueue.SendKeyin ("place smartline; xy=0,0;xy=100,100")

End Sub

Is this expected behavior? Can anyone explain what I might be doing wrong here?
