Document PdfFormat returns PDF_A_1A for a non PDF/A file

I tried the new version of Aspose.PDF for .NET (18.10) and it returns value PDF_A_1A in PdfFormat parameter of a file which is not na PDF/A but plain PDF 1.4.
Could you please check this.

Thanks for contacting support.

Would you please share sample code snippet which you have tried in your environment. We will test the scenario in share our feedback accordingly.

Dim fIsArchiving As Boolean = False
Dim Pdfdocument As New Aspose.Pdf.Document(PathName)
Select Case Pdfdocument.PdfaFormat
Case Aspose.Pdf.PdfFormat.PDF_A_1A, Aspose.Pdf.PdfFormat.PDF_A_1B, Aspose.Pdf.PdfFormat.PDF_A_2A, Aspose.Pdf.PdfFormat.PDF_A_2B, Aspose.Pdf.PdfFormat.PDF_A_3A, Aspose.Pdf.PdfFormat.PDF_A_3B
fIsArchiving = True
End Select
If fIsArchiving Then Console.WriteLine(“The file is marked as PDF/A.”)

I found out that this behaviour occurs since version 18.5
