BF2 AI Bot Names

I have figured out how to change the name of the bots in the game by modifying the mods\bf2\AI\BotNames.ai folder.  It is working great except for that some of the names are repeated with _242 or some other numbers.  I read somewhere that the names have to be two words, which they are and I have verified that there is no extra blank spaces after the names.  Any ideas of why some of the names are duplicating for bots with the _XXX numbers?
