How to Load Microsoft word content including boarder around header text and style into a radrichtextbox windows ui

Please how to Load Microsoft word content including boarder around header text and style into a radrichtextbox. I tried loading from a folder to radrichtextbox. It loads but removes the boarder around header text and does not maintain line spacing. I want it to maintain exactly what I have in the word document. Below is my attempt which loaded but did not adapt header text border style and linespace. After loading the attached file to RadRichTextBox it does not display the double boarder around the text in the header.

 Dim provider2 As DocxFormatProvider = New DocxFormatProvider()
            Using inputStream As FileStream = File.OpenRead(My.Computer.FileSystem.SpecialDirectories.MyDocuments & "\duk\Dictionary" & txtDirCount.Text & ".docx")
                Me.RadRichTextEditor1.Document = provider2.Import(inputStream)
            End Using
            Dim provider As TxtFormatProvider = New TxtFormatProvider()

            RadRichTextEditor1.LayoutMode = DocumentLayoutMode.Paged
            'Dim sectionColumnCollection As SectionColumnCollection = New SectionColumnCollection(2, 30, False) 'Without line in the middle
            Dim sectionColumnCollection As New Telerik.WinForms.Documents.Model.SectionColumnCollection(2, 75, True) ' With line in the middle
            Dim editor As RadDocumentEditor = New RadDocumentEditor(RadRichTextEditor1.Document)
            editor.ChangeSectionColumns(sectionColumnCollection)
            Dim header As New Header()
