If the rest of the hinges are already in place you've only got two choices. 1) live with it like this, or 2) cut all the hinges, reslot for new hinges, and install new hinges. Like Minn said, I doubt that it will make a big difference.

For future reference, even with the electric hinge slot cutter it's best to still check each slot before installing the hinges. See if the hinge can slide into the slot. If not, use a hobby knive (X-Acto) to clean the slot out.
