tag items on masterpage

I am using Filemaker in combination with InDesign. Filemaker produces an xml with a ROW element for every record. In each ROW, there are different fields, like NAME and CITY, each containing one or more DATA elements.

I would like to set up a masterpage with tagged frames, so that each page can contain one ROW. A frame is tagged NAME (for example) and the text in it is tagged DATA.

The problem: when I add multiple pages to the document based on the tagged masterpage, the order of the tags is messed up.

In stead of:
ROW
NAME
..DATA
CITY
..DATA
ROW
NAME
..DATA
CITY
..DATA

It becomes:
ROW
NAME
..DATA
..DATA
CITY
..DATA
..DATA
ROW

Which makes it impossible to import the xml-file.

Does anybody know how to solve this problem?

P.S.The curious thing is, that when I create the tagged layout on a non-master page, copy everything and 'paste in place' on the following pages, the tags/elements keep their correct order.
