Description:
I often use the "merge mail" functions to add codes from a database on every page of my documents for identification of the each copy.

I've notice that, if there is break and a change of page style at some point in the document, when I try to print or save the series of documents, the fields containing the records are only updated in the initial section but they are not in the following sections: the first record is maintained on every copy. If I manually click on the arrows of the merge mail toolbar, though, the records are updated correctly across the whole document. 
So I'm forced to click "next" and save a copy one by one every time I use different page style in the same document, which is frustrating and time consuming.

This bug has been present since I first started using LibreOffice, about 10 years ago.

Steps to Reproduce:
1.Create a document in Writer with a page break with a different style of page after the break, so that headers and footers can be set independently before and after.
2. Create a database containing a number of records.
3. Insert two or more "mail merge field" using the database as header or footer both before and after the break of the page.
4. Save or print mail merged documents from the mail merge toolbar, spanning several records.
 

Actual Results:
All saved or printed documents only contain the first record after the page break.

Expected Results:
The fields should be upadated across the whole document.
