    <tt>Hi Sagar,<br>
      <br>
      Thank you for your report and patience in troubleshooting this.
      Indeed, there was a bug - I just fixed it on GIT repo. <br>
      <br>
      IF you update from GIT and try again, it should be working fine.<br>
      <br>
      Please confirm.<br>
      <br>
      Many thanks and regards,<br>
    </tt>
