neorg keeps downloading tree-sitter-norg every time I open a *norg file

[umiswing]

My neorg keeps downloading tree-sitter-norg every time I open a *norg file. Is there any way to make it reproducible? I read the README.md of neorg but can't figure out how to add an update flag. Following is my init.lua:

require('packer').startup(function(use)
	use 'wbthomason/packer.nvim'
	use {
		'nvim-treesitter/nvim-treesitter',
		run = function()
			local ts_update = require('nvim-treesitter.install').update({ with_sync = true })
			ts_update()
		end,
	}
	use "nvim-lua/plenary.nvim"
	use {
		"nvim-neorg/neorg",
		tag = "*",
		-- ft = "norg",
		after = "nvim-treesitter", -- You may want to specify Telescope here as well
		run = ":Neorg sync-parsers", -- This is the important bit!
		config = function()
			require('neorg').setup {
				load = {
					["core.defaults"] = {},
					["core.norg.dirman"] = {
						config = {
							workspaces = {
								plan = "~/neorg/plan",
								example_gtd = "~/example_workspaces/gtd",
							}
						}
					},
					["core.gtd.base"] = {
						config = {
							--workspace = {"plan","example_gtd"}
							workspace = "example_gtd"
						}
					},
					["core.integrations.treesitter"] = {}
				}
			}
		end
	}
	use {
		'nvim-telescope/telescope.nvim', tag = '0.1.0',
		requires = { {'nvim-lua/plenary.nvim'} }
	}
end)
