Docx watermark shows under all content in LibreOfficeDev 4.4.4

Hi, I am trying to display a water mark in a document that can grow to multiple pages.
The requirement is to use docx, so I am stuck with than. I use docx4j to edit he document and a headless LibreOffice to save as PDF and print.

The problem is that LibreOffice renders the watermark under all content if it is in the header or in the footer.
If the watermark is in the body (document.xml), LibreOffice shows it on top but as expected it renders it on the first page only.

Is this a bug or is there a trick with the docx OpenXML tags to display it properly?

I am using the dev version as it fixes another problem with headless socket exceptions: Version:

Thank you in advance

I found a work-around - i removed all <w:shd w:color=“auto” w:fill=“auto” w:val=“clear”/> tags which made all paragraphs and table cells transparent
