Remote Event fires twice despite debounce?

Hi! I started making great progress on my game, and I completed this bomb script, but there's one thing that I haven't experienced ever with remote events. My debounce wont work. I looked at tons of other people and their ways of doing it, but it was exactly like the way I did it. I don't know if this is on the Button scripts end or if its on the Attack scripts end. It creates 2 bombs instead of one, which means double damage! Please help!

This scripts debounce won't work. Server Script, in StarterCharacterScripts.

local part = game.ReplicatedStorage.ClassData.Bloxxer.BloxxerSword:Clone()
local P = script.Parent
local fire = game.ReplicatedStorage.MoveSetFires


local A = P.ATK
local cda = false
local AF = fire.Attack
local A1 = P.AB1
local A1F = fire.AB1
local A2 = P.AB2
local A2F = fire.AB2
local RJ = P.REJ
local RJF = fire.Rejuvinate
local CORE = P.BTZ
local CF = fire.Core

	local Attackcd = false
	local AtCD = .8

A1.Changed:Connect(function(v)
	print(v)
end)
		
		local function createhitbox(position, size1, size2, size3, damage, tim, offset, plr, ray, direction)
 			local hit = Instance.new("Part")
			hit.Size = Vector3.new(size1,size2,size3)
			hit.Color = Color3.new(200,0,0)
			hit.Transparency = .6
			
			hit.CFrame = position.CFrame
			hit.Orientation = Vector3.new(0, 0, 0)
			hit.CanCollide = false
			hit.Parent = workspace
			
			if ray == true then
				
			end
			 
			local destroy = coroutine.create(function()
				wait(tim)
				if hit then
				hit:Destroy()
				end
			end) 
		coroutine.resume(destroy)
	
			hit.Touched:Connect(function(h)
				
				if h.Parent ~= plr.Character then
					if h.Parent.Humanoid then
						local humanoid = h.Parent.Humanoid or h.Parent:FindFirstChildOfClass("Humanoid")
						print(h)
						humanoid.Health = humanoid.Health - damage
						hit:Destroy()
				end
				end
			end)
		end


			print("okok")
	A1F.OnServerEvent:Connect(function(player)
	wait(.1)
	print(cda)
	if cda == false then	
	cda = true	
		if player then	
	--the hitbox
	local bomb = Instance.new("Part")
	bomb.Name = "Projectile"
	bomb.Shape = Enum.PartType.Ball
	bomb.Color = Color3.new(0,0,0)
	bomb.Size = Vector3.new(1.7, 1.7, 1.7)
	bomb.Transparency = .2
	bomb.CFrame = player.Character.HumanoidRootPart.CFrame
	bomb.Parent = workspace
	--local bv = Instance.new("BodyForce", bomb)
	
	bomb.CanCollide = false

	bomb.Velocity = player.Character.UpperTorso.CFrame.lookVector * 25
	wait(.1)
	bomb.CanCollide = true
	wait(2)

	createhitbox(bomb, 10.95, 10.95, 10.95, 15, .5, 0, player, false, nil)
	bomb:Destroy()
	--createhitbox(3.1, 2.45, 7.25, 6, .1, -8, player, false, nil)
		cda = false	
		end
	end
end)

This script works and the prints tell me this isn't the problem. Local script, in StarterCharacterScripts.

wait(5)
local UserInputService = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local char = player.Character
local mouse = player:GetMouse()
local P = script.Parent
local fire = game.ReplicatedStorage.MoveSetFires


local A1 = P.AB1
local A1F = fire.AB1
local A2 = P.AB2
local A2F = fire.AB2
local RJ = P.REJ
local RJF = fire.Rejuvinate
local CORE = P.BTZ
local CF = fire.Core

local function click(move,cd)
	print(move,cd)
	move:FireServer()
	wait(cd)
end


UserInputService.InputBegan:Connect(function(Input, Gamestuff)
   if Gamestuff then return end
--AB1
    if Input.KeyCode == Enum.KeyCode.Q then
	if A1.Value == false then 

	A1.Value = true
	click(A1F,4)
	A1.Value = false
	end
	end
--Ab2
	if Input.KeyCode == Enum.KeyCode.E then
	if A2.Value == false then
		
	A2.Value = true
	end
	end
end)

So I had a "duh" moment. Apparently, it fired twice because the fire was in Replicated storage, and that would fire for every player, not just the player in question.
