in's creed brotherhood armor of Brutus glitch ?

So I just got the armor of Brutus, and before I had this my armor was dyed florentine scarlet or whatever. Well, when I put on the armor Of Brutus in the little treasure room, that color moved to the armor. I'd have no problem with this but it's ugly as hell, and since this isn't supposed to be dyed, I can't change the color. If I do buy a new color, it just affects my other armors I put on, not Brutus.
