Converting MPX 4.0 to PDF-A1b: subtasks missing in gant chart


We try to convert MPX files to PDF-A1b format (exporting the gant chart), but the subtasks are missing in the output PDF.
To reproduce the problem we have created a new MPX 4.0 file with MS Project 4.1 on Windows XP. It contains only 2 simple task with 1-1 subtask (see screenshot input.PNG).

After that we converted this file with Aspose and the output PDF file does not contains subtasks, only tasks (see attached 4.0.PDF). We use the following save options:

        var saveOptions = new PdfSaveOptions
            PresentationFormat = PresentationFormat.GanttChart,
            Compliance = PdfCompliance.PdfA1b,
            LegendOnEachPage = false

How can we convert this file with all content?
