Why does my script clone a new object twice?

This script is inside a block.

When I click on the block with a tool it fires to server and makes the block start getting more transparent and then it's transparency ends at 1 and turns CanCollide off.

This script is inside the block and detects when the block changes transparency, and when it's at 1 it clones a bone from replicated storage to the block... But it clones twice and idk why

boneType = script.Parent.Name
debounce = false
	
script.Parent.Changed:Connect(function()
	if not debounce then
		debounce = true
		if script.Parent.Transparency == 1 then
			
			local newBone = game.ReplicatedStorage[boneType]:Clone()
			newBone.Position = script.Parent.Position
			newBone.Anchored = false
			newBone.Parent = game.Workspace.Bones
			
			print("clone")
			
		end
		
		debounce = false
	end
end)
