Not receiving the other Armor Specializations

I have not received the other Armor Specializations Engineer,Tracker,Rogue,Stalker,Pathfinder,and Pioneer though it is supposed to be released for Standard Edition players like myself who played online xbox-live from release date to 11/20, which I did.

I still only see Wetwork and Operator as locked(I’m Lvl 34 currently)but I dont see the other Specializations Engineer,Tracker,etc. as Locked options.
Do I have the choice to pick the 6 other Specializations when i actually get to lvl 50 cuz all I see are Wetwork and Operator as a locked choice.
