Part not deleting if there are duplicates of its self?

So I have a box system and when the player touches the box I want the box to destroy. It works fine if there is one box in workspace but if there is two the boxes do not delete.

m = require(game:GetService("ServerScriptService").MainModule)
spawnArea = game.Workspace:WaitForChild("BoxSpawnArea")

function newNormalBox(cash)
    box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("NormalBox"):Clone()
    box.Parent = game.Workspace
    box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))

    local AlreadyHit = false
    local function touch(hit)
        local hum = hit.Parent:FindFirstChild("Humanoid")
        if hum~=nil and AlreadyHit ~= true then
            game.Workspace.SoundsEffect.BoxHit:Play()
            AlreadyHit = true
            game.Players[m.PlayerName].leaderstats.Cash.Value = game.Players[m.PlayerName].leaderstats.Cash.Value + cash
            box:Destroy()
        end
    end
    box.Touched:Connect(touch)
end

function newGemBox(gems)
    box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("GemBox"):Clone()
    box.Parent = game.Workspace
    box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))

    local AlreadyHit = false
    local function touch(hit)
        local hum = hit.Parent:FindFirstChild("Humanoid")
        if hum~=nil and AlreadyHit ~= true then
            game.Workspace.SoundsEffect.BoxHit:Play()
            AlreadyHit = true
            m.Gems = m.Gems + gems
            box:Destroy()
        end
    end
    box.Touched:Connect(touch)
end

function newGoldBox(cash,gems)
    box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("GoldBox"):Clone()
    box.Parent = game.Workspace
    box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))

    local AlreadyHit = false
    local function touch(hit)
        local hum = hit.Parent:FindFirstChild("Humanoid")
        if hum~=nil and AlreadyHit ~= true then
            game.Workspace.SoundsEffect.BoxHit:Play()
            AlreadyHit = true
            game.Players[m.PlayerName].leaderstats.Cash.Value = game.Players[m.PlayerName].leaderstats.Cash.Value + cash
            m.Gems = m.Gems + gems
            box:Destroy()
        end
    end
    box.Touched:Connect(touch)
end

function newDiamondBox(cash,gems)
    box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("DiamondBox"):Clone()
    box.Parent = game.Workspace
    box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))

            game.Workspace.SoundsEffect.BoxHit:Play()
            AlreadyHit = true
            game.Players[m.PlayerName].leaderstats.Cash.Value = game.Players[m.PlayerName].leaderstats.Cash.Value + cash
            m.Gems = m.Gems + gems
            box:Destroy()
        end
    end
    box.Touched:Connect(touch)
end

chance = {1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,3,3,3,4}

while wait(.10) do
    a = chance[math.random(1,#chance)]
    warn(a)
    if a == 1 then
        newNormalBox(math.random(50,500))

    end
    end
    end
    game.StarterGui:SetCore("SendNotification",{
        Title = "NOTICE"; 
        Text = "A box has spawned somewhere in the map. You should go see what's inside!";
        Icon = "";
        Duration =  5;
    })
