Нужна помощь с spire.doc

---

Использование spire.doc я пытаюсь создать документ word с несколькими текстовыми полями в определенном месте на одной странице, но этот код генерирует две страницы. Кто-нибудь поможет?

string TEMPprocitano;
      private void button1_Click(object sender, EventArgs e)
      {
          citanjeReda();
      }
      public void citanjeReda()
      {
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
                {
           int brojRedova=File.ReadLines(openFileDialog1.FileName).Count();
           StreamReader sr = new StreamReader(openFileDialog1.FileName);
                    for (int i = 0; i <= brojRedova; i++)
                    {
                        TEMPprocitano = sr.ReadLine();
                        f1(); f3();
                    }
                    sr.Close();
                }
      }
      public void f1()  //doc_pers_no 11
      {
          try
          {
              StringBuilder F1 = new StringBuilder(TEMPprocitano);
              F1.Remove(0, 22);
              F1.Remove(11, 698);
              MessageBox.Show(F1.ToString());

              //Create a Word document
              Document doc = new Document();
              Section section = doc.AddSection();
              Paragraph paragraph = section.AddParagraph();

              //Append a Textbox to paragraph
              Spire.Doc.Fields.TextBox tb = paragraph.AppendTextBox(170, 20);

              //Set the position of Textbox
              tb.Format.HorizontalOrigin = HorizontalOrigin.Page;
              tb.Format.HorizontalPosition = 150;
              tb.Format.VerticalOrigin = VerticalOrigin.Page;
              tb.Format.VerticalPosition = 50;

              CharacterFormat format = new CharacterFormat(doc);
              format.FontName = "Calibri";
              format.FontSize = 11;
              format.Bold = false;



              Paragraph par1 = tb.Body.AddParagraph();
              par1.AppendText(F1.ToString()).ApplyCharacterFormat(format);

              //Save to file
              doc.SaveToFile("job.docx", FileFormat.Docx);

          }    catch (Exception){}
      }
      public void f3()   // 32
      {
          try
          {
              StringBuilder F3 = new StringBuilder(TEMPprocitano);
              F3.Remove(0, 49);
              F3.Remove(32, 650);
              MessageBox.Show(F3.ToString());
              //Create a Word document

              Document doc = new Document();
              Section section = doc.AddSection();
              Paragraph paragraph = section.AddParagraph();

              //Append a Textbox to paragraph
              Spire.Doc.Fields.TextBox tb = paragraph.AppendTextBox(170, 20);

          }    catch (Exception) { }

Что я уже пробовал:
