Re: the SINGLE PLAYER ASSIGNMENTS didnt unlock
It shows that you completed half of the single player assignments here http://battlelog.battlefield.com/bf4/soldier/Coogee400/assignments/352031974/pc/#SP_as06
And it shows that you've only completed through chapter 6\7 in the campaign here: http://battlelog.battlefield.com/bf4/soldier/Coogee400/stats/352031974/pc/
That being said I recommend to replay the last mission one more time as that sometimes triggers things to unlock. On my first two play throughs the weapons unlocked immediately, on the last weapon there was a 45 minute delay and it triggered after I replayed the last mission a 4th time.
