Exception"An item with same key has already been added" using Aspose.PDF for .NET

I am using latest version of Aspose.PDF. I am trying to convert the attached PDF file to Html. It throws error while saving the doc as html. The code I am using is given below:

PdfFileEditor pdfEditor = new PdfFileEditor();
MemoryStream[] pdfPageStreams = pdfEditor.SplitToPages(pdfStream);
for (int i = 0; i < pdfPageStreams.Length; i++)
	MemoryStream pdfPageStream = pdfPageStreams[i];
	string outFilePath = $"{guid}_{i}.html";
	using (Document doc = new Document(pdfPageStream))
		doc.Save(outFilePath, new HtmlSaveOptions
					FixedLayout = true,
					SplitIntoPages = false,
					RasterImagesSavingMode = RasterImagesSavingModes.AsEmbeddedPartsOfPngPageBackground,
					FontSavingMode = FontSavingModes.SaveInAllFormats,
					PartsEmbeddingMode = PartsEmbeddingModes.EmbedAllIntoHtml,
					LettersPositioningMethod = LettersPositioningMethods.UseEmUnitsAndCompensationOfRoundingErrorsInCss
