Why does my script only run after the second time the player dies?

I have this script which changes some leaderstats when the player dies, but for some reason, it only runs after the second time the player dies. Does anyone know why?

local players = game:GetService("Players")
local difficulty = game.Workspace.Difficulty

players.PlayerAdded:Connect(function(player)
	local leaderstats = player:WaitForChild("leaderstats")
	player.CharacterAdded:Connect(function(character)
		character:WaitForChild("Humanoid").Died:Connect(function()
			if leaderstats.Survived.Value >= 60 and difficulty.Value > leaderstats.Difficulty.Value then
				leaderstats.Difficulty.Value = difficulty.Value - 1
			end
			if leaderstats.Record.Value < leaderstats.Survived.Value then
				leaderstats.Record.Value = leaderstats.Survived.Value
			end
			leaderstats.Survived.Value = 0
		end)
	end)
end)

Sorry if the code is a bit messy. I'm fairly new to coding.
