nVerBuiltInNamesWhenSaved (2 bytes): An unsigned integer that specifies the
version number of the style names as defined by the application that writes the
file. This value SHOULD be 0.

old number is 2: which means...

"Word 97 2"

Specifying a value of 0 is recommended for maximum compatibility, as it will
cause all versions of Word to update the names to whatever set of application
defined style names is current, with little performance penalty.
