There are missing footer in EO20 version. This code was working properly in old version. Any advise?

The following are the code that I used to convert HTML to PDF.
EO.Pdf.HtmlToPdf.Options.PageSize = EO.Pdf.PdfPageSizes.A4
EO.Pdf.HtmlToPdf.Options.OutputArea = New RectangleF(0.0F, 0.0F, 8.3F, 11.7F)
AddHtmlFooter(noticeId, documentRunNo, NoticeName)
HtmlToPdf.ConvertHtml(HTMLString, PDFFileName)


This is the footer code function
Sub AddHtmlFooter(Optional ByVal NoticeId As String = "", Optional ByVal documentrunNo As String = "", Optional ByVal NoticeName As String = "")

EO.Pdf.HtmlToPdf.Options.FooterHtmlFormat = "<div style='position: absolute; top: 30.2cm; left: 6.6cm; width: 16.9cm; height: 19px; line-height: 0.45cm; text-align: center;' >" + _
"<span style='font-family: Helvetica; font-size: 8pt; font-weight: 100; '> Page {page_number} of {total_pages}</span> &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;" + _
" <span style='font-family: Helvetica; font-size: 7pt; font-weight: 100; '>" & NoticeId & "</span> &nbsp; &nbsp; " + _
" <span style='font-family: Helvetica; font-size: 8pt; font-weight: 100; '>" & documentrunNo & " </span> " + _
"</div> "

End Sub
