So ingame if I go to the archives and click through each mission they all say completed. However, I have not recieved the completionist achievement, or the general Warfield portrait for beating all 29 missions on normal.

When I go into details I get this list of missions and several say they are not done? But again, in the ingame list they are completed...not to mention of them; several are main storyline missions so they MUST have been completed in order for me to have beat the game which I have done (e.g. not little side missions) So what's the deal with that??
