For loops not producing the correct amount of outputs?

I have this module script that clones objects into workspace. For each function I ran 2 for loops so that the first for loop will always make sure a certain object gets cloned, while the second for loop will clone random items from a table.

However I have noticed that the function does not produce the correct amount of cloned objects and always produces less.

local drops = {}

--<Variables>--

local wood = game.ServerStorage.ItemDrops.Wood
local seed = game.ServerStorage.ItemDrops.Seed1

--<Tables>--

local TreeDrops = {wood, seed}

function drops.SmallTree()
	
	for i = 1, 2 do
		
		wood:Clone()
		
		wood.Parent = game.Workspace		
		
		wood:MoveTo(script.Parent.Handle.Position + Vector3.new(math.random(-3, 3), 0, math.random(-3, 3))) 		
		
	end
	
	for i = 1, 2 do
		
		local ItemDrop = math.random(1, # TreeDrops) 
		
		local Item = TreeDrops[ItemDrop]
		
		local dropped = Item:Clone()
		
		dropped.Parent = game.Workspace		
		
		dropped:MoveTo(script.Parent.Handle.Position + Vector3.new(math.random(-3, 3), 0, math.random(-3, 3))) 		
		
	end
end

function drops.MediumTree()
	
	for i = 1, 3 do
		
		wood:Clone()
		
		wood.Parent = game.Workspace		
		
		wood:MoveTo(script.Parent.Handle.Position + Vector3.new(math.random(-3, 3), 0, math.random(-3, 3))) 		
		
	end
	
	for i = 1, 3 do
		
		local ItemDrop = math.random(1, # TreeDrops) 
		
		local Item = TreeDrops[ItemDrop]
		
		local dropped = Item:Clone()
		
		dropped.Parent = game.Workspace		
		
		dropped:MoveTo(script.Parent.Handle.Position + Vector3.new(math.random(-3, 3), 0, math.random(-3, 3))) 		
		
	end
end

function drops.BigTree()
	
	for i = 1, 4 do
		
		wood:Clone()
		
		wood.Parent = game.Workspace		
		
		wood:MoveTo(script.Parent.Handle.Position + Vector3.new(math.random(-3, 3), 0, math.random(-3, 3))) 		
		
	end
	
	for i = 1, 4 do
		
		local ItemDrop = math.random(1, # TreeDrops) 
		
		local Item = TreeDrops[ItemDrop]
		
		local dropped = Item:Clone()
		
		dropped.Parent = game.Workspace		
		
		dropped:MoveTo(script.Parent.Handle.Position + Vector3.new(math.random(-3, 3), 0, math.random(-3, 3))) 		
		
	end
end

return drops

I wanted the first function to produce 4 clones, the second 6 clones, and the third 8 clones. However it doesnt seem to work 100%
