Custom Game - Number of Civs - Problem

After having a tough time beating the computer on the Noble setting, i tried to set up a custom game to have fewer civilizations to compete for land against.

Once I set four, and the next time five civilizations and closed all the other slots.

In each game, though, all 9 or so civs show up in the game. Am i doing something wrong or is there a glitch?

 

Might be a silly question, but did you scroll down on the ai slots in custom game before starting and close all the additional AI's down there? Only ask cause it took me a couple games before I realised that closing an ai in the middle doesnt cause the next ai slot to "bump up" and there were still 4 or 5 ai slots open "off screen".

 

Also, If you do all that closing of slots, and then change the map size, the ai slots will be reset to that map's default number of civs.
