Leaderboard not showing kills and deaths?

This problem has been happening since the last Roblox update. For most players in the game, the leader board for kills and deaths is not working for everyone on the server, can I get some help with this? Feedback is appreciated.

local Players = game.Players

local Template = Instance.new 'BoolValue'
Template.Name = 'leaderstats'

Instance.new('IntValue', Template).Name = "Kills"
Instance.new('IntValue', Template).Name = "Deaths"


Players.PlayerAdded:connect(function(Player)
    wait(1)
    local Stats = Template:Clone()
    Stats.Parent = Player
    local Deaths = Stats.Deaths
    Player.CharacterAdded:connect(function(Character)
        Deaths.Value = Deaths.Value + 1
        local Humanoid = Character:FindFirstChild "Humanoid"
        if Humanoid then
            Humanoid.Died:connect(function()
                for i, Child in pairs(Humanoid:GetChildren()) do
                    if Child:IsA('ObjectValue') and Child.Value and Child.Value:IsA('Player') then
                        local Killer = Child.Value
                        if Killer:FindFirstChild 'leaderstats' and Killer.leaderstats:FindFirstChild "Kills" then
                            local Kills = Killer.leaderstats.Kills
                            Kills.Value = Kills.Value + 1
                        end
                        return -- Only one player can get a KO for killing a player. Not 2, not 3. Only one.
                    end
                end
            end)
        end
