How to add new language in existing multilingual database

I have several multilingual databases from version R5 (3 languages). I have now Notes 6 and if I add new language (the fourth one) to the template and I would like to refresh database, only the first 3 languages are refreshed. If I choose replace design, the system offers me only the first 3 languages there. How can I add one more language there ? (views, forms, etc… are in 4 languages).

Thank you for fast answer
