Greatest to Least not working..?

Whenever I print the table, everything is doubled or tripled. How could It just be added to the table once?

local Items = {}

for _, Item in pairs(faceData) do
	table.insert(Items, Item.rap)
	table.sort(Items, function(a, b) return a > b end)
	for k, v in pairs(Items) do
		TextLabel.Text = v
	end
end
