Alpha Hair retexture turns white in game

Hi I'm retexturing a hairstyle I've used this hair texture on another hairstyle and done one retexture on this hairstyle and they have both worked fine.
But for some reason when I retexture this certain texture on this hairstyle it comes up fine in sims 4 studio but the hair is white in game
