Problem Converting Word Watermark to PDF

I am having a problem with a watermark that I add through Aspose.Words when I convert the Word document to PDF using Aspose.PDF.
The problem is that the watermark appears in the PDF, but it is surrounded by a border.
I am using Aspose.Words 4.1.1.0 and Aspose.PDF 3.3.2.0
Have tried everything today to get this working and am at a loss.
Your help would be appreciated.

Base test document attached

All test documents attached…
Test.doc is the base document
I then programatically add PreviewOnly.emf
I then save the resulting file as Converted_Test.doc (which looks fine)
And convert it to PDF as Test.pdf (which is where the problem appears to lie)

Hello!
Sorry for long delay.
I have addressed the issue with border appearing around the watermark. On the latest versions of Aspose components I’m unable to reproduce this. Please suggest upgrade if this issue is still relevant for you.
Aspose.Words 5.2.0:
