Combat System Dealing Damage Twice?

I made a combat punch system using Region3. However, the player you hit gets damage taken from them twice or three times in some cases. It works sometimes but other times no.

Local Script:

local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()

local UIS = game:GetService("UserInputService")
local Enabled = true
local RE = script:WaitForChild("Function")
UIS.InputBegan:Connect(function (input, GPE)
	
	if GPE then return end
	
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		if Enabled == true then
			RE:FireServer("Combat", char.HumanoidRootPart.CFrame * CFrame.new(0,0,-2.5).Position)
			Enabled = false
			wait(0.3)
			Enabled = true
		end
		
	end
end)

Server Script:

local RE = script.Parent
local Enabled = true
local combo = 1

RE.OnServerEvent:Connect(function(player, action, Pos)
	local char = player.Character or player.CharacterAdded:Wait()
	if Enabled == false then return end
	Enabled = false
	if action == "Combat" then
		if combo == 1 then
			combo = 2
			local Track = Instance.new("Animation")
			Track.AnimationId = "rbxassetid://7008354558"
			local Anim = char.Humanoid:LoadAnimation(Track)
			Anim:Play()
			local playingTracks = char.Humanoid.Animator:GetPlayingAnimationTracks()
			for i, v in pairs(playingTracks) do
				if v.Name == "walk" or v.Name == "run" then
					v:Destroy()
				end
			end
			
		elseif combo == 2 then
			combo = 1
			local Track = Instance.new("Animation")
			Track.AnimationId = "rbxassetid://7008358588"
			local Anim = char.Humanoid:LoadAnimation(Track)
			Anim:Play()
			local playingTracks = char.Humanoid.Animator:GetPlayingAnimationTracks()
			for i, v in pairs(playingTracks) do
				if v.Name == "walk" or v.Name == "run" then
					v:Destroy()
				end
			end
		end
		if char.Humanoid:FindFirstChild("Whoosh") then
			local whoosh = char.Humanoid:WaitForChild("Whoosh")
			whoosh:Play()
		else 
			local sound = Instance.new("Sound", char.Humanoid) 
			sound.Name = "Whoosh"
			sound.SoundId = "rbxassetid://231731980"
			sound.PlaybackSpeed = math.random(88, 120)/100
			sound:Play()
			
		end
			
		wait(0.2)	
		
		local region = Region3.new(Pos - Vector3.new(2.5, 2.5, 2.5), Pos + Vector3.new(2.5, 2.5, 2.5))
		local RTable = workspace:FindPartsInRegion3(region, nil, 20)
		
		for i, v in pairs(RTable) do
			if v.Parent:FindFirstChild("Humanoid") and v.Parent:FindFirstChild("Deb") == nil and v.Parent ~= char then
				local Deb = Instance.new("BoolValue", v.Parent)
				Deb.Name = "Deb"
				game.Debris:AddItem(Deb, 0.2)
				local randomDMG = math.random(20,25)
				v.Parent.Humanoid:TakeDamage(randomDMG)
				print(randomDMG)
				
				if v:FindFirstChild("Punch") then
					local punch = v:WaitForChild("Punch")
					punch:Play()
				else 
					local s = Instance.new("Sound", v)
					s.Name = "Punch"
					s.SoundId = "rbxassetid://3932505023"
					s.PlaybackSpeed = math.random(88, 120)/100
					s:Play()
				end
				local attachment1 = Instance.new("Attachment", v)
				local fx = game.ServerStorage:WaitForChild("FX")
				local punchFX = fx:WaitForChild("PUNCH")
				local random = math.random(0, 2)
				
				if random == 1 then
					
					local particle = punchFX.Effects2:Clone()
					particle.Parent = attachment1
					particle:Emit(10)
					wait(0.2)
					particle:Destroy()
					print("ELLLO")
					
				elseif random == 2 then
					
					local particle = punchFX.HitModuleParticle:Clone()
					particle.Parent = attachment1
					particle:Emit(10)
					wait(0.2)
					particle:Destroy()
					print("ELLO 2")
					
				end
				
				end
		end
		wait(0.3)
		Enabled = true
	end
