Achievements are usually glitched up and don't get handed out when they should. It's just another part of the game that the developers are working on. For now I wouldn't count on the achievements being given out when they are supposed to.
I don't know how to rank up one point for example i have 1338 but i need 1337 and they're both so close and i don't know what to do, but they're still more achievements that could be gained by rank.
