Custom chat system not filtering text and duplicating messages?

So whenever I try filtering my chat message, there are 2 issues.

1. It doesn't filter it
2. It duplicates the message whenever it puts it in the chat area (if it is the 3rd message I make, there are 3 copies, and not one.)

Here is my code.

Client:

script.Parent.FocusLost:Connect(function(enter)
	local enteredText = script.Parent.Text
	if enter then
		
		script.Parent.Text = ""
		
		game.ReplicatedStorage.Events.FilterChatMessages:FireServer(enteredText)
		
		game.ReplicatedStorage.Events.SendFilteredMessage.OnClientEvent:Connect(function(filteredText)
			-- note: this part works and puts the text on my screen!
			local text = Instance.new("TextLabel")
			text.RichText = true
			text.BorderSizePixel = 0
			text.BackgroundColor3 = Color3.fromRGB(180, 180, 180)
			text.TextColor3 = Color3.fromRGB(255, 255, 255)
			text.BackgroundTransparency = 0.5
			text.Text = '<b><i><font color="rgb(255,165,0)">'..game.Players.LocalPlayer.DisplayName..'; </font> '..filteredText..'</i></b>'
			text.Parent = script.Parent.Parent.ChatArea
			wait()
			text.Size = UDim2.new(0, text.TextBounds.X, 0, text.TextBounds.Y)
		end)
	end
end)

Server:

local textService = game:GetService("TextService")

local filteredText
local result

game.ReplicatedStorage.Events.FilterChatMessages.OnServerEvent:Connect(function(player, text)
	local success, errorMessage = pcall(function()
		filteredText = textService:FilterStringAsync(text, player.UserId)
	end)
	
	if not success then
		filteredText = "[Content Deleted]"
		print(errorMessage)
	end
	
	if filteredText:IsA("TextFilterResult") then
		result = filteredText:GetNonChatStringForBroadcastAsync()
		if result ~= text then
			print(result)
			print(text)
			result = "[Content Deleted]"
		end
	end
	
	game.ReplicatedStorage.Events.SendFilteredMessage:FireClient(player, result)
end)

Please help!

Try testing in-game since studio disables all filtering.
