I know, but that's also what I'm talking about. Once you've formed a crusade, all the icons get replaced by that sea greenish background with the cross in the upper corner. If you add new units after that, their background doesn't change to the crusade background, and if any non-crusading units are in the army, you don't get the expanded movement rate. Moving the general out and in didn't change things for me. The only way to make those new units actually "in" the crusade was to hit the Abandon Crusade button, followed by the Join Crusade button. At that point, all the units in the army became part of the crusade. I got the bonus movement again, and didn't get any extra traits as a result. But then, I haven't done that when I wasn't adding new units to the crusade, and that might be what triggers it.
