Uninstall shortcut appears then disappears

[frnds1]

For an unmanaged MSI install (project), defining an uninstall ExeFileShortcut in the start menu folder appears (sometimes) the first time, then disappears.

new Dir(@"%ProgramMenu%\MyCompany",
    new ExeFileShortcut("Uninstall My Product 1", "[System64Folder]msiexec.exe", "/x [ProductCode]") { IconFile = @"MyApp.ico" })

    <StandardDirectory Id="ProgramMenuFolder">
      <Directory Id="MyCompany" Name="MyCompany">

        <Component Id="Component.Uninstall20My20Product201_" Guid="dcd1e6ce-9a33-4daa-9992-a2edd259f225" Bitness="always64">
          <Shortcut Id="MyCompany.Uninstall20My20Product201_" WorkingDirectory="System64Folder" Target="[System64Folder]msiexec.exe" Arguments="/x [ProductCode]" Name="Uninstall My Product 1.lnk" Icon="IconFile1_MyApp.ico" IconIndex="0" />

          <CreateFolder />
          <RemoveFolder Id="MyCompany" On="uninstall" />

          <RegistryKey Root="HKCU" Key="Software\WixSharp\Used">
            <RegistryValue Value="0" Type="string" KeyPath="yes" />
          </RegistryKey>
        </Component>

      </Directory>
    </StandardDirectory>

The project has 2 exes that have their own shortcuts in the folder that appear in the start menu folder. It is only the uninstall shortcut that does not want to hang around.

The problem occurs with Wix#3 and Wix#4 (unmanaged).
