After an initial test with the licensed latest version of Aspose.Words for .NET i.e. 19.5, we were unable to reproduce this issue on our end. We would suggest you please upgrade to the latest version of Aspose.Words for .NET. Hope, this helps.
See sample input/output documents. docs.zip (150.1 KB)
We used the following simple code on our end for testing:
Document doc = new Document("E:\\temp\\HTMLPage1.html"); doc.Save("E:\\Temp\\19.5.docx"); doc.Save("E:\\Temp\\19.5.pdf");
In case you still observe the problem on your end, please also provide a comparison screenshot highlighting the problematic areas in Aspose.Words generated PDF and attach it here for our reference.
