Data Storing Doesn't Update For Some Players On My Game, Why?

I Have Tested My Game, In Roblox Studio And It Works Perfectly, Even In The Roblox Itself, The Problem Is For some Players When They Reach The Finish They Won't Get Any Point, Or The Point Will Be Given To Any Other Player, Why?

print("starting")
local datastore = game:GetService("DataStoreService")
local ds1 = datastore:GetDataStore("CashSaveSystem")

game.Players.PlayerAdded:Connect(function(player)
 local folder = Instance.new("Folder", player)
 folder.Name = "leaderstats"
 local wins = Instance.new("IntValue", folder)
 Finished.Name = "Finished"
 Finished.Value = ds1:GetAsync(player.UserId) or 0
 ds1:SetAsync(player.UserId, Finished.Value)

workspace.FinishPart.Touched:Connect(function()
            Finished.Value = Finished.Value + 1


    end
end)



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



end)
