It is ok, we will only render one item with the word template.
yes, this is expected, making it works with more than one item is not possible because of Docx limitations, even with MS Word you can not get a different header/footer per page, the header/footer of it is limited to mostly static content, and it allows just dynamic parts for special fields like page count, current page, etc.
About the word template closed in the footer, do you mean the new version still can not work ? or should I do anything ?
the new jsreport versions won't work with the same template you have, you need to change it to this:
docxList is opened and closed in the same document, the footer part needs that you make an explicit reference to the data with {{Projects.0.Address1}} for example
