Strange behavior with appcmd list config "" -section:requestFiltering

I have a Windows 2008 R2 server that when running this command:

appcmd list config "<SITE>" -section:requestFiltering

returns the following instead of the web site requestFiltering

<system.ftpServer>
  <security>
    <requestFiltering>
      <fileExtensions>
      </fileExtensions>
      <requestLimits />
      <hiddenSegments>
      </hiddenSegments>
      <denyUrlSequences>
      </denyUrlSequences>
    </requestFiltering>
  </security>
</system.ftpServer>

If I run the same command on a different Windows 2008 R2 server, that server returns the expected information:

<system.webServer>

I only get this information on the 1st server if I fully qualify the section by running the command as:

appcmd list config "<SITE>" -section:/system.webServer/security/requestFiltering

I'm trying to figure out why it is working differently on this server. Any suggestions?

Thanks,
