Event Firing Again and again after fired once??? XP Notification

Im having this issue: My notify script where its meant to pop up with this specific level up message which it does but once it does it just loops and loops . Its meant to fire each time a new level. help!

LevelNotify Script:

GUI:WaitForChild("LevelUp").Event:connect(function(lvl)
    if allow and Enabled.Value then
        allow = false
        Frame.Visible = false
        Label.Text = "LEVEL UP!"
        Level.Text = "NEW LEVEL!"
        local LVL_HUE = math.clamp(tonumber(lvl) or math.random(1, 10) * 100, 1, 1000) / 1000 * 0.8333333333333334
        local color = Color3.fromHSV(LVL_HUE, 1, 1)
        for i, v in ipairs(Lines) do
            v.BackgroundColor3 = color
            v.BackgroundTransparency = 1
        end
        for i, v in ipairs(Lines_LVL) do
            v.BackgroundColor3 = color
            v.BackgroundTransparency = 1
        end
        Frame.Position = UDim2.new(0.5, 0, 0.45, 0)
        Label.TextTransparency, Level.TextTransparency = 1, 1
        Label.TextColor3, Level.TextColor3 = color, color
        animateGUI()
        allow = true
    end
end)

THE script where i fire the xp notification:

function LevelNotify(lvl)
    Player.PlayerGui.LevelNotify.LevelUp:Fire(lvl)
end
function onLevelUp(lvl)
    Info.XP.Bar.Level.Text = "LEVEL "..lvl
    setLevel(lvl)
end

Database.Notify.OnClientEvent:connect(function(action,...)  
    local vars = {...}
    if action == "new tp" then
        sfx("tick")
        onPointsAdded(vars[1])
    elseif action == "new level" then
        sfx("tick")
        onLevelUp(vars[1])
        LevelNotify(vars[1])
    elseif action == "new xp" then
        sfx("tick")
        onXPChange(vars[1])
    end
end)

onLevelUp(sendControl("get level"))
onPointsAdded(sendControl("get tp"))
onXPChange(sendControl("get xp"))

All i need is for it to stop looping and only fire when u hit "new level".
