Bug report for Words.dll v21.4

Hi, Support:
Is this a bug?

Dim Doc As New Aspose.Words.Document("C:\Temp\Test.docx")
 Dim FontSize as integer
 Dim FontSize2 as integer
 Dim IsFontBold as boolean
 For Each para As Global.Aspose.Words.Paragraph In Doc.FirstSection.Body.GetChildNodes(Global.Aspose.Words.NodeType.Paragraph, True)
              FontSize =   para.ParagraphFormat.Style.Font.Size 
             para.ParagraphFormat.Style.Font.Size=40
             FontSize2=   para.ParagraphFormat.Style.Font.Size 
              para.ParagraphFormat.Style.Font.Bold = true
                IsFontBold  =para.ParagraphFormat.Style.Font.Bold
             exit for
        Next
        Doc.Save("C:\Temp\Test.docx")

Bugs ?
Why the FontSize2 is equal to FontSize , whereas the FontSize2 should be 40?
Why the IsFontBold is equal to false , whereas the IsFontBold should be true?

Are they bugs? Please investigate it.
