Why is this lootframe flashing when multiple is killed?

So i'm making a looting system and i have it so a lootbag is being cloned to the killed's position and when the player's torso's magnitude is less then 10 or 10 then the lootframe is visible otherwise it's not but it just flashes the lootframe when multiple enemies is killed why? And there is no errors and everything works if it wouldent start flashing if multiple enemies is killed

Here is the server script:

Remotes["TakeDamage"].OnServerEvent:connect(function(player, hit, g, dmg)
    if hit.Parent:FindFirstChild("Humanoid") then
        hit.Parent:FindFirstChild("Humanoid"):TakeDamage(dmg)
    end
    hit.Parent:FindFirstChild("Humanoid").Died:connect(function()
        local lootbag = game.ReplicatedStorage.Lootbag:Clone()
        lootbag.Parent = hit.Parent:FindFirstChild("Lootbags")
        lootbag.Name = "Lootbag "..hit.Parent.Name
        lootbag.CFrame = CFrame.new(hit.Parent:FindFirstChild("Torso").Position)

        local playerGui = player.PlayerGui
        local LootFrame = playerGui:WaitForChild("ScreenGui").LootFrame
        local looted = false
        LootFrame.LootButton.MouseButton1Click:connect(function()
            looted = true
            lootbag:Destroy()
        end)
        while true do
            if (player.Character.HumanoidRootPart.Position - lootbag.Position).magnitude <= 10 then
                LootFrame.Visible = true
                LootFrame.Frame.TextLabel.Text = lootbag.Name
                LootFrame.Position = UDim2.new(0.5, 0, 0.5, 0)
                if looted then
                    break
                end
            else
                LootFrame.Visible = false
            end
            wait()
        end
    LootFrame.Visible = false
    end)
end)
