Hello, I've hit a roadblock concerning squadrons and trying to unlock it.

I am Second Serpent Lieutenant, and have all 3 ranks completed in the hunting log for order of the Twin Adder. There is no quest available with the personnel officer/quartermaster. I'm no longer able to apply for a promotion as it says I'm at maximum allowable rank. Also, am level 71 in my job
Please help, what am I missing?!
