T-705 Missing developer menu topic

So i have gone into the about section and tapped the build number many times, had the message saying im a developer etc

There is no menu, or at least i cant see one, I assume it should appear in the general tab under the heading system?

If i press build number again it just tells me No need, developer mode has been enabled.
I have rebooted the tablet
Any suggestions?

Android version 4.4.2
Baseband T705XXU1ANF7
kERNAL 3.4.39-2293707
Build number KOT49H.T705XXU1ANG2
