I do not know why. please help me check this problem.

I attched file pdf ‘filepdfdoducment.pdf’ and a document report test result form internet ‘ProblemWithValidatePdfFile.docx’.
Please see attached file in detail ‘Problem_With_ValidatePdf.zip’ Problem_With_ValidatePdf.zip (478.9 KB)

This is my source code validate by aspose:

private static void ValidatePDF()
{

        Console.WriteLine("run validate!!!!!");
        string dataDir = "PdfFilesToMerge/";
        //string inputFileName = dataDir + "StructureElements.pdf";
        string inputFileName = dataDir + "filepdfdoducment.pdf";
        string outputLogName = dataDir + "ua-21110.xml";
        DateTime start = DateTime.UtcNow;
        using (var document = new Aspose.Pdf.Document(inputFileName))
        {
            //bool isValid = document.Validate(outputLogName, Aspose.Pdf.PdfFormat.PDF_UA_1);
            bool isValid = document.Validate(outputLogName, Aspose.Pdf.PdfFormat.PDF_A_1A);

        }
        DateTime end = DateTime.UtcNow;
