Arceus Problem

So i gave my Arceus a Pixie Plate just to see the different sprite, and then took it away, and it didn’t change back. This happened with giratina and the Griseous Orb, but that reverted after one battle. My Arceus is just stuck a fairy type. Any way i could make it normal again? And also It doesn’t change into primal when holding when in this bugged form. I am not holding the plate, yet am still fairy and crystal does nothing, although i see the primal symbol under the Arceus name. Changing plates does change its sprite and type, however when taking away the plate it retains the type and still can’t go Primal.

Did you find any fix? Have the same issue
