How do i make the datastore save values that arent under "leaderstats"?

I can't seem to get my script to work I don't want these values to show in leaderstats so I tried to save it from a different folder in the same location as leaderstats

local DSService = game:GetService("DataStoreService"):GetDataStore("Q14ER056")
game.Players.PlayerAdded:Connect(function(plr)
    local key = plr.Name
    local cmdsets = Instance.new("Folder", plr)
    local savevalue = Instance.new("BoolValue")
    cmdsets.Name = "Rankings"
    savevalue.Parent = cmdsets
    savevalue.Name = "IsAdmin"
    local getsaved = DSService:GetAsync(key)
    if getsaved then
        savevalue.Value = getsaved[1]
    else
        local NumbersToSave = {savevalue.Value}
        DSService:SetAsync(key, NumbersToSave)
    end
end)

game.Players.PlayerRemoving:Connect(function(plr)
    local key = plr.Name
    local ST = {plr.cmdsets.IsAdmin.Value}
    DSService:SetAsync(key, ST)
end)
