Possible Bug, 'Fairie Artisans'

Card copies a creature put on the battlefield by opponent, but when it does so its supposed to exile all other tokens created by Fairie Artisans.
Currently it just copies whatever creatures come into play, but ignores the other token exile efect, unless im crazy or missing something.
