Dotted Bullets Appear before Paragraphs after PPTX to PPT Conversion in C#

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

The most affected slides:

  • 1: unintended dotted bullets in front of each paragraph.
  • 2: unintended dotted bullets in front of each paragraph.
  • 10: unintended dotted bullets in front of each paragraph.

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

Code sample:

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

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.
