Failed to validate PDF/A file after export from presentation document

When I export specific file to pdfa1-b, online validator validation fails. I use Aspose.Slides for .Net 20.10. The code for conversion is below:

var doc = (new Aspose.Slides.PresentationFactory()).ReadPresentation(inputStream);
var options = new Aspose.Slides.Export.PdfOptions
                   {
                       Compliance = Aspose.Slides.Export.PdfCompliance.PdfA1b
                   };
doc.Save(outputStream, Aspose.Slides.Export.SaveFormat.Pdf, options);

inputStream and outputStream are instances of System.IO.MemoryStream.

Here is my input and output files Files.zip (61.4 KB)
