You are talking about 'default' profile and that you messed it up.

Just to be sure (as it was not mentioned):
You are aware that there are two occurences of default (and all other profiles)?
One at /usr/share/kernel-power-settings/
and once more at /home/user/.kernel/

Possibly you messed up the one in /home by saving but 'restored' the one in /usr? The one in /home have higher priority (are in front of the search path).
Please check also the contents of /etc/default/kernel-power (the profile loaded at boot).
