Export of UML class association diagram to grafic file (PNG, SVG, etc...) creates strange figures

        var diagram = new Aspose.Diagram.Diagram("Test.vsdx");

        var opt = new ImageSaveOptions(Aspose.Diagram.SaveFileFormat.PNG)
        { PageIndex = 0};

        opt.Resolution = 300;
        diagram.Save("UML.png", opt);

See attached: Test.vsdx and UML.png

I use version of .Net Aspose.Diagram.dll.
