CRM Mail merge issues

CRM Mail merge issues

How do you configure the page on mail merge, from ZCRM??. I have written a template and structured the filters. the print preview is on one page. 

I merge the document. 

The merge reformats and then the document formatting moves higher and higher until by page 5 you have two half letters!!! 

Very frustrating. Does anyone know if I need to insert a page break or how to correct /format this so it doesn't happen??

Help.
