About textFragment.Rectangle's wrong coordinates

In some cases,“textFragment.Rectangle” does not seem to reflect the real position,resulting big offset. The attached file is the case.
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(“经济”);
textFragmentAbsorber.TextSearchOptions.IsRegularExpressionUsed = true;
pdfDocument.Pages.Accept(textFragmentAbsorber);
TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;

        foreach (TextFragment textFragment in textFragmentCollection)
        {
           
             
                Aspose.Pdf.Rectangle myrectange;
                myrectange = textFragment.Rectangle;
             

                    RedactionAnnotation ra = new RedactionAnnotation(textFragment.Page, myrectange);
                   

                            textFragment.Page.Annotations.Add(ra);
                            ra.FillColor = textFragment.Page.Background;
                            ra.Color = textFragment.Page.Background;
