you're using Bot Changer, are you not? At least that's what the bottom lines of your aidefault folder indicate...

ops:
To
Pte. Brown - you said "That's the file you want, but you need to add the line:
aiSettings.overrideMenuSettings 1
This will override the in-game sliders/settings."
But it's already on there...

Here's what my aidefault folder currently looks like - with ratio at 100, Players set to 1, it was 1 vs 48...

ops:
rem *** PRSP Ai v5 ***
aiSettings.setNSides 2
aiSettings.setAutoSpawnBots 1
rem aiSettings.setMaxNBots 64
rem aiSettings.maxBotsIncludeHumans 1
rem aiSettings.setBotSkill 0.4
rem To spawn more than 15 bots in SP, use the following lines instead of the three lines above.
rem Note that this is totaly unsupported, it will affect your system's performance
rem and may even crash your game. That being said, you will most likely be able to run a lot
rem more bots than 15 on your system.
rem Example for 32 bot game with expert bots
aiSettings.overrideMenuSettings 1
aiSettings.setMaxNBots 86
aiSettings.maxBotsIncludeHumans 0
aiSettings.setBotSkill 0.9
rem BotSkill 1.0 is the highest it will go
