I think he/she means that someone used a foreign program to change another Pokémon to a Rotom or create two Pokémon out of one.

You can tell it is duped if the date is after 2015

I don't think you can change it back. The most you can do probably is get a mod or an admin to give you a Rotom in exchange for the duped one
