Number of AI players moddable?

I'm playing BM1.11 and the latest SEV patch (1.63?) Early on in my SEV playing, I decided that I didn't like the number of AI players I was being placed against in the single player game (amongst other things), so I went into settings.txt (in the BM 1.10+ folder) and changed the numbers a bit, to reflect my tastes. Namely, lots of neutrals (9 or 10 for each setting, low, medium, or high), and what I feel to be an appropriate number of "main" AI races as well.

Problem is, the number of races I'm seeing still doesn't match what should be appearing according to settings.txt. The last game I generated have 5 neutrals and 3 main races, when it should have been at least 9 neutrals and 5 main races. And this isn't the only game I've generated where I've noticed this. Is there another setting someplace that I'm missing, or did I modify the wrong settings.txt file? I'm not quite sure what to make of it.
