If a player leaves mid-game/pings the games they play get poofed, so that might have caused it to be less than 3 games played if that player was fighting for most of the war. Also be sure you set up the war in the right server, which may have been another reason for this.
Also the clan war system is full of glitches, although usually it will just mess up the score of the war.
That's all I know of right now that could have caused this. =\
EDIT: Oh ya and I also believe that all of the members of the clan have to be opped for their games to record.
