Welcome to the forum!
I have never read anything like this before. Butterfield is unit #563 in the database models with the usual Strat 3 Off 1 Def 1 and a seniority of 53. The one who fits that is the real Butterfield and the other is a glitch most likely. You might send him in a ship to the shipping lanes where he can cause you no confusion.
I'm the 51st shade of gray. Eat, pray, Charge!
