OBED Scaling Matrix, what?

Every time I export my Demoiselle, I get a message saying "The object has an OBED Scaling Matrix prepended to it. This unnecessary and should not be done."
I guess it isn't NECESSARY to remove it
, but what is it, and how would I go about taking it off?
Its apparently on the frame/fuselage of the aircraft, which is just a whole bunch of cylinders.
