Walking Dead xbox problem

I just noticed while playing episode 3, my episode 2 achievements are not adding right. When i look at my achievements from the dashboard, it shows only 23 of 24 achievements after finishing episode 3. When i open and look at the indivaul achievements, all 24 are showing unlocked. Any clue? I have only one save and only one playthough.
