Office setup installs Skype for Business although it is excluded

Question

Hi,

I have used the webbased Office tool to create an XML for installing Office apps: https://config.office.com/deploymentsettings

There I chose not to install Skype for Business, Groove and Bing.

I got this XML:

<Configuration ID="9629df3b-37fa-4985-b1d9-325db22c01a5">
  <Add OfficeClientEdition="64" Channel="MonthlyEnterprise" MigrateArch="TRUE">
    <Product ID="O365ProPlusRetail">
      <Language ID="MatchOS" />
      <Language ID="zh-tw" />
      <Language ID="en-us" />
      <Language ID="fr-fr" />
      <Language ID="de-de" />
      <ExcludeApp ID="Groove" />
      <ExcludeApp ID="Lync" />
      <ExcludeApp ID="Bing" />
    </Product>
    <Product ID="VisioProRetail">
      <Language ID="MatchOS" />
      <Language ID="zh-tw" />
      <Language ID="en-us" />
      <Language ID="fr-fr" />
      <Language ID="de-de" />
      <ExcludeApp ID="Groove" />
      <ExcludeApp ID="Lync" />
      <ExcludeApp ID="Bing" />
    </Product>
    <Product ID="ProjectProRetail">
      <Language ID="MatchOS" />
      <Language ID="zh-tw" />
      <Language ID="en-us" />
      <Language ID="fr-fr" />
      <Language ID="de-de" />
      <ExcludeApp ID="Groove" />
      <ExcludeApp ID="Lync" />
      <ExcludeApp ID="Bing" />
    </Product>
    <Product ID="LanguagePack">
      <Language ID="MatchOS" />
      <Language ID="zh-tw" />
      <Language ID="en-us" />
      <Language ID="fr-fr" />
      <Language ID="de-de" />
    </Product>
  </Add>
  <Updates Enabled="TRUE" />
  <RemoveMSI />
  <AppSettings>
    <User Key="software\microsoft\office\16.0\excel\options" Name="defaultformat" Value="51" Type="REG_DWORD" App="excel16" Id="L_SaveExcelfilesas" />
    <User Key="software\microsoft\office\16.0\powerpoint\options" Name="defaultformat" Value="27" Type="REG_DWORD" App="ppt16" Id="L_SavePowerPointfilesas" />
    <User Key="software\microsoft\office\16.0\word\options" Name="defaultformat" Value="" Type="REG_SZ" App="word16" Id="L_SaveWordfilesas" />
  </AppSettings>
  <Display Level="None" AcceptEULA="TRUE" />
</Configuration>

So now I run setup.exe /configure configuration.xml and Office installs just fine.

But Skype for Business and Groove are being installed, too. Why? Any ideas?
