Slide number issue in PPTX to PDF


I’m evaluating Aspose Slides product to convert PowerPoint 2007 (PPTX) to PDF. Although most of the objects render correctly in PDF, we hit a dead end when dealing with slide numbers inherited master slide setting. Slide numbers on all slides are displayed as ‘<#>’. The same thing works correctly for ppt files. Is this a known issue in PPTX to PDF? Is there a fix available without writing too much custom code?

Please advice.

Thank you!
