add file twice

I am using Aspose.pdf to replace text in a pdf with file attachments.  I want the attachments to show up in 2 places, someplace in the doc and at the end of the doc.  The code that I have written add the file twice but the second one is corrupt for some reason.  I would like to only add the file once and just point to the correct file.  Why is the second file corrupt?

            var textToFind = new Aspose.Pdf.Text.TextFragmentAbsorber(file.FileGuid.ToString());            pdfDocument.Pages.Accept(textToFind);            var textFragmentCollection = textToFind.TextFragments;            foreach (Aspose.Pdf.Text.TextFragment guidText in textFragmentCollection)            {                //find the first instance of the GUID and replace it with the icon and label                guidText.Text = string.Empty;                var textRect = guidText.Rectangle;                var page = guidText.Page;                var x = (float)textRect.LLX;                var y = (float)textRect.LLY;                //6x12 is the size of the icon                var fileAttachment = new Aspose.Pdf.InteractiveFeatures.Annotations.FileAttachmentAnnotation(                    page,                    new Aspose.Pdf.Rectangle(x, y, x + 6, y + 12),                    new Aspose.Pdf.FileSpecification(newFile, file.FileName, labelName))                {                    Icon = Aspose.Pdf.InteractiveFeatures.Annotations.FileIcon.Paperclip                };                page.Annotations.Add(fileAttachment);                //add the appendix name near the icon                //the 20 is to add bit of space next to the icon                var textFragment = new Aspose.Pdf.Text.TextFragment()                {                    Position = new Aspose.Pdf.Text.Position(x + 20, y),                    Text = labelName                };                textFragment.TextState.FontSize = 12;                textFragment.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("Arial");                textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(Color.Black);                var textBuilder = new Aspose.Pdf.Text.TextBuilder(page);                textBuilder.AppendText(textFragment);            }
