Is it necessary to have my full name (including middle name) on my student pilot license? So my student pilot license is missing a middle name, but my drivers license, written exam, and passport all have it printed.

I've spoken with the DPE, and he says it may be an issue, or it may not, and that he is going to look into it.

I've called FSDO, airmen certification branch, and other DMVesque organizations, and they all seem to say the same thing: 


  Oh, you need to talk to (insert amorphous bureaucracy here)


Does anyone know who I actually need to talk to, or if this is even an issue? Do I just need to call FSDO and insist that they fix the issue, or what?

The DPE said that with the written exam being OK it may be a non-issue. Would love to hear from a DPE on here if possible.
Alright so here is the outcome: 

I called FSDO, spoke with a real nice guy who told me to give him a call if I couldn't handle this online.

Called a zillion bureaucracies, all telling me to call someone else.

Called the nice guy at FSDO, set up an appointment for a name correction not a name change. Went to the appointment and was in and out in under an hour.

If you're having the same issue, I would recommend bringing every official identification you've got: passport, birth certificate, drivers license, etc.

Tl;DR call FSDO and tell them you need a name correction. NOT a name change. Can't stress that enough.
