I don't see where you found an error. They don't say the aircraft is for Spain - Seville is the city where all A400M are assembled.
I think it is here in the words in the article -
These first large elements of the aircraft, known as MSN44, were transported by ship from the UK where they were made to St Nazaire, France and then flown to Seville inside a specially designed giant Airbus Beluga aircraft. MSN44 will shortly enter into the final assembly process in preparation for its delivery to the Spanish Air Force in the second quarter of 2016.
OK, thank you, I missed the end of the last sentence.
