Open XML SDK to instantiate Word template with macros : either bad formatting or non-working macros

**Describe the bug**
When instantiating a Word document based on a template which contains macros, either the formatting is not preserved or the macros are duplicated and not functionning.

**Screenshots**
Template with correct top part

Instance created with bad top part

Instance created with duplicated VBA macros

**To Reproduce**
```c#
var templatePath = @".\MyTemplate.dotm";
```
*First try : LAYOUT IS NOT PRESERVED FROM THE TEMPLATE AND MACRO WORKS FINE*
```c#
string tempFileName = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName() + ".Try1.docm");
File.Copy(templatePath, tempFileName, true);

using (var wordDocument = WordprocessingDocument.Open(tempFileName, true))
{
wordDocument.ChangeDocumentType(WordprocessingDocumentType.MacroEnabledDocument);
wordDocument.Save();
}
```
*Second try : LAYOUT IS NOT PRESERVED FROM THE TEMPLATE AND MACRO WORKS FINE*
```c#
tempFileName = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName() + ".Try2.docm");

using (var wordDocument = WordprocessingDocument.CreateFromTemplate(templatePath, false))
{
wordDocument.ChangeDocumentType(WordprocessingDocumentType.MacroEnabledDocument);
wordDocument.SaveAs(tempFileName).Dispose();
}
```
*Third try : LAYOUT IS PRESERVED FROM THE TEMPLATE BUT MACROS ARE DUPLICATED*
```c#
tempFileName = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName() + ".Try3.docm");

using (var wordDocument = WordprocessingDocument.CreateFromTemplate(templatePath))
{
wordDocument.ChangeDocumentType(WordprocessingDocumentType.MacroEnabledDocument);
wordDocument.SaveAs(tempFileName).Dispose();
}
```

**Observed behavior**
Either the formatting of the instance is not correct or the VBA macros are not working because they seem to be duplicated.

**Expected behavior**
An instance of the document with a correct formatting and working macros.
