once again, specializations have disapeared

I am currently at SR95, mid way through wet work. Before the last halo 4 update i had Tracker, Engineer and Operator (i had completed all others, excluding wetwork). as of now i only have Operator remaining as Tracker and Engineer have disappeared. I have tried restarting both console and halo 4 and re-downloading the Infinity Actual Code and Specializations Priority Alpha, however to no avail, any ideas?

Dude they will fix everything on there new update

I just got to 70, completed both Wetwork and Operator, thinking that the rest or the next would show up when I got to 70. No other specializations are available to choose, even though the game tells me to choose another one. Kinda BS. Errors are starting to pile up throughout Halo 4.
