DGN to PDF. Some of the elements of referenced DGN documents are not visible in the result pdf document

Product: PDFNet, CADModule

Product Version: 9.2.7.9274

Some of the elements of referenced DGN documents are not visible in the result pdf document.

I am using trial version of PDFNet library for .NET Framework. I am using .NET Framework 4.0. I am trying to convert DGN document with 4 refernces to pdf file and some of the items of referenced documents are not visible. Is it a limitation of trial version of the product? I will provide source code and attachments.

using pdftron;
using pdftron.PDF;
using pdftron.SDF;

namespace PDFTron
{
    internal static class Program
    {
        public static void Main()
        {
            PDFNet.Initialize(@"demo:license_key");
            PDFNet.AddResourceSearchPath(@"D:\PDFTronCad\Lib");

            using (var pdfDoc = new PDFDoc())
            {
                Convert.FromCAD(pdfDoc,
                    @"D:\Attachments\Demo Flow Diagram 4 References.dgn", null);
                pdfDoc.Save(@"D:\Attachments\output.pdf", SDFDoc.SaveOptions.e_remove_unused);
            }
        }
    }
}
