Datastore stats not saving, despite changes. Am I missing an easy fix?

I'm having trouble trying to figure out why the saving function in my datastore script isn't working. The script is a normal script object located in ServerScriptService. I can edit my stats manually when testing, but when save functions are carried out, the return values are the ones that are already saved and apparently just get saved again despite being changed. My code is as follows:

local DataStoreService = game:GetService("DataStoreService")
local StatStore = DataStoreService:GetDataStore("StatData")



local function saveData(player)
    local dataTable = {
        player.stats.Cash.Value;
        player.stats.Level.Value;
        player.stats.XP.Value
    }

    for i,v in pairs(dataTable) do
        print(i .. "index current value set to: " .. v)
    end

    local success, err = pcall(function()
        StatStore:SetAsync(player.UserId, dataTable)
        for i,v in pairs(dataTable) do
            print(i .. "index value now set to: " .. v)
        end
    end)

    if success then
        print("Data was saved!")
    else
        print("Data was not saved!")
        warn(err)
    end
end

--[[manual save function
game.Workspace.SavePart.Touched:Connect(function(player1)
    local player = game:GetService("Players"):GetPlayerFromCharacter(player1.Parent)
    saveData(player)
end)
]]


game.Players.PlayerAdded:Connect(function (player)
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "stats"
    leaderstats.Parent = player

    local cash = Instance.new("IntValue")
    cash.Name = "Cash"
    cash.Parent = leaderstats

    local level = Instance.new("IntValue")
    level.Name = "Level"
    level.Parent = leaderstats

    local xp = Instance.new("IntValue")
    xp.Name = "XP"
    xp.Parent = leaderstats


    local data
    local success, err = pcall(function()
        data = StatStore:GetAsync(player.UserId)
    end)

    if success and data then
        print("Player has saved data! " .. data[1] .. "dollars, " .. data[2] .. " levels, and " .. data[3] .. " XP.")
        cash.Value = data[1]
        level.Value = data[2]
        xp.Value = data[3]
    else
        print("Player has no saved data.")
    end
end)




game.Players.PlayerRemoving:Connect(function(player) --save on leave
    local success, err = pcall(function()
        saveData(player)
    end)
    if success then
        print("Data has been saved upon player leaving.") --this prints but no actual data changes
    else
        print("Data was NOT saved upon player leaving.")
    end
end)



game:BindToClose(function() --crash save
    for _, player in pairs(game.Players:GetPlayers()) do
        local success, err  = pcall(function()
            saveData(player)
        end)

        if success then
            print("Data has been saved upon shutdown!")
        else
            print("Data has not been saved upon shutdown!")
        end
    end
end)
