I have converted a *.ppt presentations to *.pptx format with Aspose.Slides and the result document have a few inconsistencies.

The most affected slides:

6101811261171.ppt

  • 5: incorrect bullet style.
  • 13: extra numbering in paragraphs.

PeopleCentric_Leadership.ppt

  • 35: incorrect bullet style.

strategyshow.ppt

  • 15: incorrect bullet style

There are screenshots of these issues in the attached archive, as well as, the presentations.

Code sample:

var pr = new Presentation(inPath);
pr.Save(outPath, SaveFormat.Pptx);

I use Aspose.Slides.dll 25.2.0.0 and Microsoft® PowerPoint® for Microsoft 365 MSO (Version 2501 Build 16.0.18429.20132) 64-bit.
