Redirecting to debian-boot; debian-project is for project-wide 
discussions rather than this sort of thing.

This sounds as though perhaps you tried to do the preseeding using a 
method that's only processed after the locale and keyboard questions 
have been asked.  
https://www.debian.org/releases/stable/amd64/apbs01.en.html#preseed-methods 
explains this, and offers two different suggestions on how to handle it.

https://www.debian.org/releases/stable/amd64/apbs04.en.html#preseed-l10n 
should describe the set of options, bearing in mind the above.
