The config for en.labs clearly includes 

    $wgGroupsRemoveFromSelf = array( 'editor', 'reviewer' );

But twice now I have added the 'reviewer' group (renamed "uber-reviewer" there, don't get confused) and had it jump into the "groups you cannot modify" column.  This was the case for a considerable length of time until one day it reappeared in the available groups - if you check my rights history there you can see my log summary of "finally!" or something like that.  I recently readded the 'reviewer' right and it has once again become locked in the 'on' position.  This *may* have something to do with an interplay between 'reviewer' and 'sysop', as I haven't noticed this problem on either of my other accounts there.
