Visual Studio .vstemplate files not copying files using $projectname$ parameter - visual-studio

Question

I am having trouble getting Visual Studio project templates to work correctly.
I have edited the .vstemplate file in order to allow VS to rename project files when a new project is created from the template.
Some of the files are not copied or renamed when the new project is created.
I have a C++ project named Minimal that I have exported as a template.
I am currently NOT using any replaceable parameters in the Minimal template project.
The Minimal.zip folder in the Project Templates directory contains:
__TemplateIcon.ico (created by VS when the project was exported)
Minimal.cpp (my code)
Minmal.rc (a resource file containing a string table with one entry)
Minimal.vcxproj (created by VS at project creation time),
Minimal.vcxproj.filters (created by VS at project creation time)
MyTemplate.vstemplate (an XML file created by VS when the project was exported)
resource.h (created by VS at project creation time).
The MyTemplate.vstemplate file looks like this after editing:
<VSTemplate Version="3.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005" Type="Project">
<TemplateData>
<Name>Minimal</Name>
<Description><No description available></Description>
<ProjectType>VC</ProjectType>
<ProjectSubType>
</ProjectSubType>
<SortOrder>1000</SortOrder>
<CreateNewFolder>true</CreateNewFolder>
<DefaultName>Minimal</DefaultName>
<ProvideDefaultName>true</ProvideDefaultName>
<LocationField>Enabled</LocationField>
<EnableLocationBrowseButton>true</EnableLocationBrowseButton>
<Icon>__TemplateIcon.ico</Icon>
</TemplateData>
<TemplateContent>
<Project TargetFileName="Minimal.vcxproj" File="Minimal.vcxproj" ReplaceParameters="true">
<ProjectItem ReplaceParameters="false" TargetFileName="$projectname$.vcxproj.filters">Minimal.vcxproj.filters</ProjectItem>
<ProjectItem ReplaceParameters="false" TargetFileName="$projectname$.cpp">Minimal.cpp</ProjectItem>
<ProjectItem ReplaceParameters="false" TargetFileName="resource.h">resource.h</ProjectItem>
<ProjectItem ReplaceParameters="true" TargetFileName="$projectname$.rc">Minimal.rc</ProjectItem>
</Project>
</TemplateContent>
</VSTemplate>
I edited the ProjectItem entries to use the $projectname$ parameters.
Two ProjectItems have ReplaceParameters set to "false" and a TargetFileName set to $projectname$.
One ProjectItem has ReplaceParameters set to "false" and TargetFileName unedited.
One ProjectItem has ReplaceParameters set to "true" and TargetFileName set to $projectname$.
I have a project named Test that I created from the Minimal template.
I would expect the Test project folder to contain one file for each ProjectItem, and the files that use the $projectname$ parameter to be renamed as Test.something.
The Test project folder actually contains this:
Test.sln (created by VS)
resource.h (not renamed, as expected)
Test.vcxproj (renamed, as expected)
Test.vcxproj.filters (renamed, as expected)
Test.vcxoproj.user (created by VS).
The Test project folder does not contain any .cpp or .rc file.
I have also tried not using $projectname$ for the .cpp file and the .rc file, and just used their original names, and they get copied into the new project.
Does anyone know what I need to do to make it work correctly with renamed files?
