Help With DataStore?

I'm currently using DataStore to store two things: Inventory and wins/coin counting.

When it comes to the wins and the coins, it saves fine, but when it comes to saving a few other variables I'm using for an Inventory, it doesn't work so well.

It works in game, but once I leave the data resets. Help?

Joining game/loading data

local DataStore = game:GetService("DataStoreService"):GetDataStore("WarGamesSaver")

game.Players.PlayerAdded:connect(function(player)
	
	local leaderstats = Instance.new("Model", player)
	leaderstats.Name = "leaderstats"
	
	local cash = Instance.new("IntValue", leaderstats)
	cash.Name = "Coins"
	
	local wins = Instance.new("IntValue", leaderstats)
	wins.Name = "Wins"
	
	local InvoSlot1 = Instance.new("StringValue", player)
	InvoSlot1.Name = "Slot1"
	InvoSlot1.Value = "Default"
	
	local InvoSlot2 = Instance.new("StringValue", player)
	InvoSlot2.Name = "Slot2"
	InvoSlot2.Value = "Empty"
	
	local InvoSlot3 = Instance.new("StringValue", player)
	InvoSlot3.Name = "Slot3"
	InvoSlot3.Value = "Empty"
	
	local InvoSlot4 = Instance.new("StringValue", player)
	InvoSlot4.Name = "Slot4"
	InvoSlot4.Value = "Empty"
	
	local Equiped = Instance.new("StringValue", player)
	Equiped.Name = "Equiped"
	Equiped.Value = "Default"
	
	
	local key = "player-"..player.userId
	
	local savedValues = DataStore:GetAsync(key)
	
	if savedValues then
		cash.Value = savedValues[1]
		wins.Value = savedValues[2]
	else
		local valuesToSave = {cash.Value, wins.Value, InvoSlot1.Value, InvoSlot2.Value, InvoSlot3.Value, InvoSlot4.Value, Equiped.Value, }
		DataStore:SetAsync(key, valuesToSave)
	end
	
	
	
end)

Leaving game/saving data

local DataStore = game:GetService("DataStoreService"):GetDataStore("WarGamesSaver")

game.Players.PlayerRemoving:connect(function(player)
	
	local key = "player-"..player.userId
	
	local valuesToSave = {player.leaderstats.Coins.Value, player.leaderstats.Wins.Value, player.Slot1.Value, player.Slot2.Value, player.Slot3.Value, player.Slot4.Value, player.Equiped.Value}
	DataStore:SetAsync(key, valuesToSave)
	
	
end)

It has trouble saving saving everything except for "coins" and "wins"
