Chat isn't censoring in my game. I'm not in studio why is this happening?

To start off. I'm NOT in studio. I tried to use this code in a local script, It's in the workspace. Maybe that's the problem: Here's the code so you can look at it!

-- LocalScript

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local player = Players.LocalPlayer
local playerGui = player:WaitForChild("PlayerGui")
local screen = playerGui:WaitForChild("MessageScreen")
local sendMessageEvent = ReplicatedStorage:WaitForChild("SendPrivateMessage")

-- GUI elements for send frame
local sendFrame = screen:WaitForChild("SendFrame")
local recipientField = sendFrame:WaitForChild("Recipient")
local writeMessageField = sendFrame:WaitForChild("Message")
local sendButton = sendFrame:WaitForChild("Send")

-- GUI elements for receive frame
local receiveFrame = screen:WaitForChild("ReceiveFrame")
local senderField = receiveFrame:WaitForChild("From")
local readMessageField = receiveFrame:WaitForChild("Message")

-- Called when send button is clicked
local function onSendClicked()
    -- Try to find the recipient. Only want to send message if recipient exists
    local recipient = Players:FindFirstChild(recipientField.Text)
    local message = writeMessageField.Text
    if recipient and message ~= "" then
        -- Send the message
        sendMessageEvent:FireServer(recipient, message)
        -- Clean up send frame
        recipientField.Text = ""
        writeMessageField.Text = ""
    end 
end

-- Called when send message event fires meaning this client got a message
local function onReceiveMessage(sender, message)
    -- Populate fields of receive frame with the sender and message
    senderField.Text = sender.Name
    readMessageField.Text = message
end

-- Bind event functions
sendButton.MouseButton1Click:Connect(onSendClicked)
sendMessageEvent.OnClientEvent:Connect(onReceiveMessage)

-- Server Script

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TextService = game:GetService("TextService")

local sendMessageEvent = ReplicatedStorage.SendPrivateMessage

local function getTextObject(message, fromPlayerId)
    local textObject
    local success, errorMessage = pcall(function()
        textObject = TextService:FilterStringAsync(message, fromPlayerId)
    end)
    if success then
        return textObject
    end
    return false
end

local function getFilteredMessage(textObject, toPlayerId)
    local filteredMessage
    local success, errorMessage = pcall(function()
        filteredMessage = textObject:GetChatForUserAsync(toPlayerId)
    end)
    if success then
        return filteredMessage
    end
    return false
end

-- Called when client sends a message
local function onSendMessage(sender, recipient, message)
    if message ~= "" then
        -- Filter the incoming message and send the filtered message
        local messageObject = getTextObject(message, sender.UserId)

        if messageObject then
            local filteredMessage = getFilteredMessage(messageObject, recipient.UserId)
            sendMessageEvent:FireClient(recipient, sender, message)
        end
    end
end

sendMessageEvent.OnServerEvent:Connect(onSendMessage)
