[TTT] I'm having issues adding buttons to the radio menu for the traitor weapon.

[Impitt]

Basically when I change the 'cl_radio.lua' to add my new sound jihad="radio_button_jihad" and added

local smatrix = {
   {"scream", "burning", "explosion", "footsteps"},
   {"pistol", "shotgun", "mac10", "deagle"},
   {"m16", "rifle", "huge", "jihad", "beeps"}
};

It appears in the radio menu and plays the correct sounds (in the other file ttt_radio.lua) but says Error:Translation instead of saying Jihad.
Anyone one know what the problem is?
