Multiple Texts appear instead of only one?

[qMrSpooky (Nox)]

Can’t really explain this, but I have a Subtitle script I made and when the player touches (not really touches, I use magnitude) or “falls down” to a point, a Subtitle is supposed to appear.
Problem is, all 3 subtitles appear at once, any fix?

Touch Script (Server-side)

local RS = game:GetService("ReplicatedStorage")
local Events = RS:WaitForChild("Events")
local FellEvent = Events:WaitForChild("Fell")

local fell = 0
local db = false
local Player
local Character
local Magnitude

game:GetService("Players").PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		Player = plr
		Character = char
	end)
end)

while task.wait() do
	if Character then
		Magnitude = (script.Parent.Position - Character.PrimaryPart.Position).Magnitude
		if Magnitude < 35 then
			if db == true then return end
			Character:SetPrimaryPartCFrame(workspace.Part1.Teleport.CFrame)
			FellEvent:FireClient(Player, fell)
			fell += 1
			task.wait(0.5)
			db = false
		end
	end
end

I think it is because you forgot to set the debounce to true in the server’s script. There is no db = true under if db == true then return end.

@qMrSpooky

if Magnitude < 35 then
    if db == true then return end

    -- (Set the debounce to true here).

    Character:SetPrimaryPartCFrame(workspace.Part1.Teleport.CFrame)
    FellEvent:FireClient(Player, fell)
    fell += 1
    task.wait(0.5)
    db = false
end

I’m sorry, I fixed it in the end. Apparently I had an extra AddSubtitle() somewhere that I forgot.
