Problem act 3 campain

Hi, I’m sorry for my English, I have a problem in Act 3 of the campaign to get an “achievement”, to gather all the improvements of Jack, I got all except one, the definitive ability of “camouflage”, the game does not It allows me to take it and I already did everything to try to get it.

pd: I just want the achievement and I don’t want to play the whole campaign again just because of that definitive ability
