Npc que era pra vender spell, não vende

Olá, estou usando atualmente em meu server o sistema de spells por trade, do vodkart: 

Eu editei um pouco e está assim no meu ot:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}
function onCreatureAppear(cid) npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid) npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg) npcHandler:onCreatureSay(cid, type, msg) end
function onThink() npcHandler:onThink() end
function creatureSayCallback(cid, type, msg)
if(not npcHandler:isFocused(cid)) then
return false
end
local talkUser = NPCHANDLER_CONVbehavior == CONVERSATION_DEFAULT and 0 or cid
local shopWindow = {}
local spells = {

{id=1950, buy = 900, name = "Exori Mort", spell_name = "Death Strike", vocations = {1}, level = 9},

{id=6103, buy = 1500, name = "Exevo Flam Hur", spell_name = "Fire Wave", vocations = {1}, level = 9},

No meu server não tem promotion, e tem magias editadas como se percebe. Também já editei todas no spells.xml, para os players terem que comprarem pra usá-las.

Eu to testando aqui e, só as duas primeiras spells da lista dão para comprar, as outras eu gasto dinheiro mas não consigo soltar a spells =x
