Migradoc

Hi I'm trying to generate a pdf with some data (header, paragraph, table, footer etc.) using PDFSharp+Migradoc where the table data is taken from a WPF datagrid. But whenever there are many rows in the table the footer text is overlapping with table data and if the PDF goes to next page then header text is overlapping with table data (sample pdf: https://filebin.net/u78dhz0ngwhh1pdh)

How do I fix this?

What I have tried:

//PDF maker helper Methods
      void AddHeader(MigraDoc.DocumentObjectModel.Section se, string text, int size, bool addBorder = false)
      {
         MigraDoc.DocumentObjectModel.Paragraph pa = se.Headers.Primary.AddParagraph();
         pa.AddFormattedText(text, TextFormat.Bold);
         pa.Format.Alignment = ParagraphAlignment.Center;
         pa.Format.Font.Name = "Times New Roman";
         pa.Format.Font.Size = size;
         pa.Format.Font.Color = MigraDoc.DocumentObjectModel.Colors.Blue;
         
         if (addBorder)
         {
            pa.Format.Borders.Bottom = new MigraDoc.DocumentObjectModel.Border() { Width = "0.5pt", Color = MigraDoc.DocumentObjectModel.Colors.DarkGray };
         }

      }


      void AddParagraph(MigraDoc.DocumentObjectModel.Section se, string text, ParagraphAlignment alignment, int size)
      {
         MigraDoc.DocumentObjectModel.Paragraph p = se.AddParagraph();
         p.AddFormattedText(text);
         p.Format.Alignment = alignment;

         p.Format.Font.Size = size;
      }
