How many pins does USB 3.0 Header have?

[Craterloads]

As above, mine appears to have one missing and the opposite side connected doesnt appear to have any holes blocked off, can anyone just have a quick look and see if the pins are complete or do they all have one missing? Thanks

Thats the thing, none on the plug are shielded
