i'm interesting in your product and during some tests i found a strange behaviuor when exporting to PDF format.
In my template document, i have a simple table with 2 rows as header (they should be repeated on each page) and a row that is the region filled with "MailMerge.ExecuteWithRegions"´s method. First page is ok, but in the others the header´s rows are not present.
I found it strange because on your "aspose.words features" document about version 5.2.1 it was supported.
Am i doing someting strange ?
PS: I´m testing versione 6.3.0 on .NET 2.0
