Aspose.PDF is wrong when set new value for metadata

[xucongli1989]

Env

• Windows 10 .NET 4.7
• Aspose.PDF for NET 22.12

Q1

Aspose get a wrong result when set a new metadata value for KeyWords, steps:

• PDF has a metadata KeyWords, its value is DDD
• Change new value for KeyWords to 444
• It get a wrong result, it became 444; DDD, the except result should be 444

Q2

Aspose overwrites original Creator and Producer content, and I didn’t actually change them.
Creator became to Aspose Pty Ltd. and Producer became to Aspose.PDF for.NET 22.12.0.

Code

    var doc = new Aspose.Pdf.Document(@"C:\Users\XCL\Desktop\test\source.pdf");
    doc.Info.Title = "111";
    doc.Info.Author = "222";
    doc.Info.Subject = "333";
    doc.Info.Keywords = "444";
    doc.Save(@"C:\Users\XCL\Desktop\test\target.pdf");
