GameTooltip Issue

[sgkdnay]

Trying to understand GameTooltip but for some reason not working as intended (reading tooltips)

function vQC_ToolTips(self)
	local lines = self:NumLines()
	print(lines)
	for i = 1, lines do
		local txtL = getglobal(self:GetName() .. "TextLeft" .. i)
		if txtL:GetText() ~= nil then
			if txtL:GetText() == "Quest ID" then
				local txtR = getglobal(self:GetName() .. "TextRight" .. i)
				print("Found it "..txtR:GetText())
			end
		end
	end
end
GameTooltip:HookScript("OnShow", vQC_ToolTips)

Some would give me information, other will not.
This will NOT give me QuestID into chat, also x.Numlines shows 3 when it's 11

But this one will, while this x.NumLines shows 12 properly

So what am i missing? Im trying to extract all information from whomever's addon's tooltip created
