I did not have that problem. We got gumshoe and junior detective one night. Saved/quit and finished off super sleuth and legendary campaign the next night. According to the achievement guide the achievements are attained by beating a specific mission but I think that is incorrect. I cannot say for sure I will have to wait for other people to post since I already have all the achievements. Or if anyone else cares to say something please do
