a couple of things are not working with my leaderboard please help me?

Im currently trying to make a basic leaderboard that displays name, kills and deaths. the text there is controlled by the leaderstats values but it worked for a little bit but now it keeps giving me and error that says, leaderstats is not part of the player but when i go check in the explorer tab i have the leaderstats loaded into the player.

Another issue is i want the text to update with the amounts of deaths or kills but the way i do it, im not sure how to have it update. Can you please help me out with this -TeaWithMee

Leaderboard code

game.Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:Connect(function(char)
        local clone = game.StarterGui.LeaderBoard.RedList.Listin:Clone()
        local parent = game.StarterGui.LeaderBoard.RedList
        clone.Parent = parent
        clone.PlrName.Text = plr.Name
        clone.Kills.Text = plr.leaderstats.Kills.Value
    clone.Deaths.Text = plr.leaderstats.Deaths.Value
    end)
end)
