[Secret Terminal in Halo Waypoint and how to get it]

I have all the terminals, unlocked Threshold and watched it, no achievement has popped up, it has said I have got all these credits, but my balance has not changed, nor has any achievement popped up on my screen. What am I doing wrong. Also all the videos are in my archive? Is this a glitch? Help 343i?
