LeaderBoard Wins, Won't Be Updated, Any Help?

So I Have done Some Parkour, And When You Reach the End, You Get + 1 Win, For Some Players, It Works, But For Some It Doesn't, It Doesn't Count as a Win or It Gives The Win To Someone Else, Any Help?

local datastore = game:GetService("DataStoreService")
local ds1 = datastore:GetDataStore("winsSaveSystem")--change all "wins" to what value you want and keep doing it 
local Debounce = tick() -- Assign tick() to the variable
game.Players.PlayerAdded:Connect(function(player)
 local folder = Instance.new("Folder", player)
 folder.Name = "leaderstats"
 local wins = Instance.new("IntValue", folder)
 wins.Name = "Wins"
 wins.Value = ds1:GetAsync(player.UserId) or 0
 ds1:SetAsync(player.UserId, wins.Value)

workspace.Lobby.DROPDOWN.Winner.Touched:Connect(function()
    if (tick() - Debounce) >= 2 then -- Make sure 5 seconds have elapsed since last debounce
        Debounce = tick()
            wins.Value = wins.Value + 1


    end
end)



 wins.Changed:Connect(function()
  ds1:SetAsync(player.UserId, wins.Value)
 end)



end)
