Galarian Darumaka evolved into normal Darmanitan

[Infecti0n_]

Hi, I don't know how this happened but I used an ice stone to evolve my galarian Darumaka but it became a normal Darmanitan upon evolution. Why did this happen and would it be possible to get it devolved so I can fix it? My IGN is Infecti0n_ and I am playing on the Emerald Realm.

Thanks
