Lua trigger/brush help!

[MarioDox]

Pratically I'm trying to do a TF2 Passtime thingy, but, when I tried replacing the doors ("trigger_passtime_ball") that don't exists, the trigger extends to a specific point. Strangely, I didn't put any type of script/code for extending it.

--shared
ENT.Type             = "brush"
ENT.Base = "base_brush"
ENT.PrintName        = ""
ENT.Author            = ""

ENT.Spawnable            = false
ENT.AdminSpawnable        = false

--init
AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )
include( 'shared.lua' )

function ENT:Initialize()  
    self:SetTrigger(true)
end
function ENT:StartTouch(ent)
end
function ENT:EndTouch(ent)
end
function ENT:KeyValue( key, value )
end
function ENT:Think()
end

cl_init is empty.

This is what I get:
