Using the debug mode i found that Zamazenta has a typing mistake he is fairy and not fighting type but this occurred only in is base form the shield form is fighting and steel like he normaly is i think what appened was that Zacian was copyed and then edited to be Zamazenta changing the sprite , ability and moves that he can learn but they may have forgot to change the fairy type i think if i didnt had the debug mode nobody woulde've have noticed that and i hope it will be fixed soon.
