DataStore saves in studio, but not in servers?

My DataStore for settings is not saving properly, and I have no clue why. I've tried changing keys and DataStore names, and that doesn't seem to be doing anything. Loading works fine because I tried editing it through a plugin that lets you edit your DataStores, so I know it's not the loading part of the script. I have an AutoSave that uses the spawn() function, I don't know if that is conflicting with the player left, but I don't know.

Here my saving part of my code.

PlayerRemoving save:

--The DataStore key is using:
local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("Settings")

local settings = player:WaitForChild("Settings")

local key = "User-"..player.userId -- User-(playerid) is what I am currently using, I was using player-(playerid) before.

local valuesToSave = {
    settings.MusicEnabled.Value, settings.MusicVolume.Value
}
DataStore:SetAsync(key, valuesToSave)
print("Stats successfuly saved!")

Autosave:

spawn(function()
    while wait(autosaveInterveal) do
        print("Now autosaving!")
        for i, player in pairs(game.Players:GetPlayers()) do

            local settings = player:WaitForChild("Settings")

            local key = "User-"..player.userId

            local valuesToSave = {
                settings.MusicEnabled.Value, settings.MusicVolume.Value
            }
            DataStore:SetAsync(key, valuesToSave)
        end
        print("Autosave complete")
    end
end)

All of the code is in the same script.

Edit: My game is FilteringEnabled.

Thanks for the help! ~Marco
