Why my bullet markers are stacking up?

Hello,

As I said in the title,I made a bullet marker script using RayCast but when I shoot to same place multiple times,the bullet holes are stacking up.How can I fix this?Thanks.

game.ReplicatedStorage.RayCastEvent.OnServerEvent:Connect(function(Player, FromP, ToP,Target)
 local RayCast = Ray.new(FromP,(ToP-FromP).unit*100)
 local ignoreList = workspace.bh:GetChildren() -- folder with all the bullet holes
 table.insert(ignoreList,Player.Character) -- player's character
 local Part,Position,Normal = game.Workspace:FindPartOnRayWithIgnoreList(RayCast,ignoreList, false,true)
 local Dist = (ToP-FromP).magnitude
 if not Dist then Dist = 300 end
--[[
 local Lazer = Instance.new("Part")
 Lazer.Parent = game.Workspace
 Lazer.Anchored = true
 Lazer.CanCollide = false
 Lazer.Size = Vector3.new(0.1,0.1,Dist)
 Lazer.CFrame = CFrame.new(FromP,Position)*CFrame.new(0,0,-Dist/2)
--]]
 local Hole = game.ReplicatedStorage.Hole:Clone()
 Hole.Parent = Part.Parent
 Hole.Position = ToP
Hole.CFrame = CFrame.new(Hole.Position, Hole.Position+Normal)

 local Weld = Instance.new("Weld")
 Weld.Part0 = Part
 Weld.Part1 = Hole
 Weld.C0 = Part.CFrame:Inverse()
 Weld.C1 = Hole.CFrame:Inverse()
 Weld.Parent = Hole
 game.Debris:AddItem(Hole,10)



-- game.Debris:AddItem(Lazer,0.2)
--[[
 if Part and Part.Parent:FindFirstChild("Humanoid") then
  Part.Parent.Humanoid:TakeDamage(30)
 end
--]]

end)
