Can't unmap F14/F15 from brightness

I just got a new MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports) and with it came Sierra (10.12.1). When using a full size external keyboard keys F14 and F15 control monitor brightness. I believe this used to be configurable in the keyboard shortcut prefs, but I can't see them there anymore. I am wanting to turn them off to use for custom functions. Any ideas?

Here's the fix!

This was really annoying me too, and here's how I fixed it. Apparently the Display option only appears in System Prefs > Keyboard > Shortcuts when a non-Apple keyboard is attached to your Mac. I plugged in a Dell USB keyboard, did the little dialog box / walk-through to recognize (identify) it, and opened System Prefs. The Displays option magically showed up, allowing me to un-check F14 & F15 for monitor brightness. And the setting sticked when I swapped back to my Apple keyboard. I can think of no good reason that this option is hidden when using an Apple KB, but there you go!

It's got to be a bug. At least, I'd sure consider it one. There's no logical reason to remove the option on certain models. And you certainly don't want them there if you've used something like a Spyder or i1 Display Pro to properly calibrate and profile your monitor. You move the brightness after that, and the monitor profile no longer means anything.

I agree and I don't think the feature was meant to be removed on certain models. What I do think is possible is Sierra doesn't install correctly on all models. I've read enough posts on here to have a feeling not all the issues some users have are due to incompatible software. Maybe differences in microcode or some interactions somewhere. I don't know. Gives me a headache thinking about it.
