I would most certainly verify that the plugs are correct type, that they appear physically the same, and that a crush washer was used on the offending plug on the offending side.

Following that I'd inspect the threads in the head for a previous repair. There could be a Time-sert (thread repair method, Google it)
That may have threaded in too far allowing the plug electrode to contact the piston.

If everything seems normal, just put 2 crush washers on that plug (to raise it up) and take it for a ride.
