Achievements and rankings confuse me.

Firstly, is there a way to see what achievements you have already got next to the ones you have yet to achieve? I just see a bunch of them listed together, and I don't know if I've earned them or not.

And the ranking confuse me further because they don't appear to be in the correct numeral order. Loco is up there at rank 70 and I'm rank 54. Shouldn't it be 1 and 16 respectively?

Group ranking is off too. Arm of Joe hasn't been active since 2010, yet is in the top three groups. Wth? I know it's probably still being worked on, but that's what I noticed.
