Why do my coins only save when they go higher??

For some reason, my coins in the game only save whenever they are increased. When they are decreased and I leave the game it loads back at what the coins used to be before they were decreased. I tried a solution to fix this which was save the coins whenever they changed but it didn't work. I also tried playing in Roblox studio and Roblox itself but it didn't work.

Also sometimes the floors dont save.

Server Script

local DataStoreService = game:GetService("DataStoreService")

local GameDataStore = DataStoreService:GetDataStore("GameDataStore")

local Players = game:GetService("Players")

local function leaderboardSetup (player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local Coins = Instance.new("IntValue")
	Coins.Name = "Coins"
	Coins.Value = 0
	Coins.Parent = leaderstats
	
	local Floors = Instance.new("IntValue")
	Floors.Name = "Floors"
	Floors.Value = 0
	Floors.Parent = leaderstats
	
	local Items = Instance.new("Folder")
	Items.Name = "Items"
	Items.Parent = player
	
	local SC = Instance.new("IntValue")
	SC.Name = "SC"
	SC.Parent = Items
	SC.Value = 0
	
	local TimeT = Instance.new("IntValue")
	TimeT.Name = "TimeT"
	TimeT.Parent = Items
	TimeT.Value = 0
	
	local data
	local data2
	local success, errormessage = pcall(function()
		data = GameDataStore:GetAsync(player.UserId.."Floors")
		data2 = GameDataStore:GetAsync(player.UserId.."Coins")
	end)
	
	if success then
		Floors.Value = data
		Coins.Value = data2
		print("YAY UR DATA LOADED UWU")
	else
		print("NO NO NO DATA DINDT LOAD THIS ISNT GOOD SADYWFDYUWADYAGDWYUIDuwu...")
		warn(errormessage)
	end
end


Players.PlayerAdded:Connect(leaderboardSetup)

Players.PlayerRemoving:Connect(function(player)
	
	local success, errormessage = pcall(function()
		GameDataStore:SetAsync(player.UserId.."Floors",player.leaderstats.Floors.Value)
		GameDataStore:SetAsync(player.UserId.."Coins",player.leaderstats.Coins.Value)
	end)
	
	if success then
		print("Data saved! OMG SO MUCH UWUW NOISES CONGRATS")
	else
		print("OH NO DATA NO SAVED SAD WUYD*AWDGUIWDOAYWDIUYAWD")
		warn(errormessage)
	end
end)

First of all a question: Why would you use remote events? You could just save them in the Script. Also another tipp: you dont actually have to write all of the parents in these lines local

TimeT = Instance.new("IntValue") 32 TimeT.Name = "TimeT" 33 TimeT.Parent = Items 34 TimeT.Value = 0

you could write this instead TimeT = Instance.new("IntValue",Items) TimeT.Parent = Items

Now to your problem.

Well as far as I can tell you are using the .Changed event of the Values wich only trigger when as the name already says the Value is changed. I would suggest only saving player data when they leave and or in periods of a vew minutes. Saving data each time a Value changes is highly inefficient. If you really care about having data saved at all time then you should check out Datastore2. Now I also suggest to use a BindToClose() function wich triggers saving data in case the server shuts down. Also maybe you should consider using Update async instead of SetAsync since SetAsync is just overwriting the data, wich could be fatal.

so what you could do is to put this in your script (NOT the local script) and just delete the part with the remote event. I also suggest that you follow my advice and make my suggested changes to the script:

Players.PlayerRemoving:Connect(function(player) 

 local success, errormessage = pcall(function()
59	        GameDataStore:SetAsync(player.UserId.."Floors",player.leaderstats.Floors.Value)
60	        GameDataStore:SetAsync(player.UserId.."Coins",player.leaderstats.Coins.Value)
61	    end)
62	 
63	    if success then
64	        print("Data saved! OMG SO MUCH UWUW NOISES CONGRATS")
65	    else
66	        print("OH NO DATA NO SAVED SAD WUYD*AWDGUIWDOAYWDIUYAWD")
67	        warn(errormessage)
68	    end


end)

I hope this helped you out,
