I've created a mail merge document which is A3 size.  Using tables (4 coloumns x 5 rows) formatted for use on namebadges(8.9cm x 5.5 cm), which I have been using for a long while and have only recently noticed it is deleting files

Data is collected from an Excel Spreadsheet, typically coloumns are headed "First Name", "Surname" and "Company".  The "Word Fields" I put into the cell are the corresponding fields from the spreadsheet, plus <<Next Record>>

The merge works perfectly, except for one thing.  Imagine I have 25 records (names) and I merge this information into this document, which has 20 cells in the table (the template for my namebadges), when I count the final number of name badges I have 23.  After a bit of investigation, what seems to be happening is that it is missing out the first data record, followed by every "20th" record.  In other words, whatever record should have appeared in the first cell (1st coloumn/row) gets deleted and subsequently the following record appears in that cell.  This happens with every new page

Does anyone know how I get around this, without having to retype these names?
