Please try the same conversion on the last versions of our components:
Aspose.Words 4.4.0.0 and Aspose.Pdf 3.5.8.0.
That’s not a good practice to format document content with empty paragraphs, spaces etc. It’s better to set spacing before and after, indents in the Paragraph Properties. But if you get affordable results on the latest versions you can retain all this.
Regarding the tick marks I’ll investigate the issue and will let you know whether we can control this.
