Kills leaderboard problem, help?

I made Kills leaderstats for whenever you kill a player and/or a bot, and it works perfectly fine until someone else joins the server. If another person joins the server, it completely pauses your kills leaderstats and only the other person can earn kills.

Here is the game: https://www.roblox.com/games/4708400827/Sword-fighting-AI-Testing-v2 I have made it 5 player servers so you can test it out with other people for yourself.

Here is my leaderboard script:

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
                    end
                end
            end)
        end
    end)
    game.Workspace:WaitForChild("Bot1").Bot.Humanoid.Died:Connect(function()
        local BotHumanoid1 = game.Workspace:WaitForChild("Bot1").Bot.Humanoid
        for i, Child in pairs(BotHumanoid1:GetChildren()) do
            if Child:IsA('ObjectValue') and Child.Value 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
            end
        end
    end)
    game.Workspace:WaitForChild("Bot2").Bot.Humanoid.Died:Connect(function()
        local BotHumanoid2 = game.Workspace:WaitForChild("Bot2").Bot.Humanoid
        for i, Child in pairs(BotHumanoid2:GetChildren()) do
            if Child:IsA('ObjectValue') and Child.Value 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
            end
        end
    end)
end)

Thank you!
