Problem in Replace Text Function

Sad [:(]

In my project we are supposed to edit the contents of pdf files.I am using replace function as follows:

Aspose.Pdf.Kit.PdfContentEditorobjExtrac = new Aspose.Pdf.Kit.PdfContentEditor();

objExtrac.BindPdf(@"C:\Documents and Settings\sridivya\Desktop\M719.pdf");

objExtrac.ReplaceText("<<>>", "ReplacedText");

I am facing an issue where the newly replaced text (i.e "ReplacedText " in my case) is overlapping, The text is not replaced clearly.

Please can anyone suggest solution for my problem.

Please attach M719.pdf here for testing.

I will investigate it and reply to you soon.
