Different First-Page Headers Preserved in Single File Output

We've fixed an issue where Word templates configured with a different header for the first page did not behave correctly when generating documents as a Single File with Page Breaks. Previously, only the first page of the combined document displayed the designated first-page header, while subsequent merged records incorrectly continued using the standard header. With this update, each merged record now correctly retains its own first-page header and subsequent page headers, ensuring consistent formatting throughout the generated document.
