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"
