Data tag being removed after PDF to TIFF conversion

We are currently using Aspose.PDF version 21.12.0.0 in .NET and are experiencing an issue during PDF to TIFF conversion. Specifically, all data tags on the PDF document are completely removed after the conversion. Could you please investigate this issue and let us know if there are any options available to resolve it?

   // Open document
                pdfDocument = new Document(strSourceFile);

                // Create TiffSettings object
                TiffSettings tiffSettings = new TiffSettings
                {
                    Compression = CompressionType.None,
                    Depth = Aspose.Pdf.Devices.ColorDepth.Default,
                    Shape = ShapeType.None,
                    SkipBlankPages = false
                };

                // Create TIFF device
                TiffDevice tiffDevice = new TiffDevice(resolutionPDF, tiffSettings);

                // Convert a particular page and save the image to stream
                tiffDevice.Process(pdfDocument, strDestFile);
                pdfDocument.Dispose();
