Indentation increases with each item

Describe the bug

I'm having a hard time determining if this is intended or not...but it's really annoying and I'm not sure how to disable it, or if I'm just doing something wrong. The problem is that when I'm writing a list, instead of being on the same indentation level, it adds one on the new line. This is super confusing, and it also happens when org_indent_mode is set to noindent.

Steps to reproduce

When I start a list like so (| = cursor):

- List Item|

Then I press enter, I would expect this:

- List Item
|

But instead I get this:

 - List Item
   |

This means that repeatedly adding items gets each one indented an additional level, which is not what I want. If I want another level, I'll add one myself...

Expected behavior

Explained above.

Emacs functionality

Not really sure...I'm not an emacs user, and I'm not in a position to install it and check at the moment, but what demo videos I can find online do not seem to function the way this plugin does...though I think they're doing something more clever that I'm not sure is possible with neovim at all at the moment (with virtual indents and whatnot).

Minimal init.lua

The template works: https://github.com/nvim-orgmode/orgmode/blob/master/scripts/minimal_init.lua

vim.cmd([[set runtimepath=$VIMRUNTIME]])
vim.cmd([[set packpath=/tmp/nvim/site]])

local package_root = '/tmp/nvim/site/pack'
local install_path = package_root .. '/packer/start/packer.nvim'

local function load_plugins()
  require('packer').startup({
    {
      'wbthomason/packer.nvim',
      { 'nvim-treesitter/nvim-treesitter' },
      { 'kristijanhusak/orgmode.nvim', branch = 'master' },
    },
    config = {
      package_root = package_root,
      compile_path = install_path .. '/plugin/packer_compiled.lua',
    },
  })
end

_G.load_config = function()
  require('orgmode').setup_ts_grammar()
  require('nvim-treesitter.configs').setup({
    highlight = {
      enable = true,
      additional_vim_regex_highlighting = { 'org' },
    },
  })

  vim.cmd([[packadd nvim-treesitter]])
  vim.cmd([[runtime plugin/nvim-treesitter.lua]])
  vim.cmd([[TSUpdateSync org]])

  -- Close packer after install
  if vim.bo.filetype == 'packer' then
    vim.api.nvim_win_close(0, true)
  end

  require('orgmode').setup()

  -- Reload current file if it's org file to reload tree-sitter
  if vim.bo.filetype == 'org' then
    vim.cmd([[edit!]])
  end
end

if vim.fn.isdirectory(install_path) == 0 then
  vim.fn.system({ 'git', 'clone', 'https://github.com/wbthomason/packer.nvim', install_path })
  load_plugins()
  require('packer').sync()
  vim.cmd([[autocmd User PackerCompileDone ++once lua load_config()]])
else
  load_plugins()
  load_config()
end

Additional context

No response

Use the provided minimal init.lua with Neovim 0.8.1 and reproduce pressing Enter after an Org list item, including with org_indent_mode set to noindent. Trace the list and newline indentation behavior; done means repeatedly creating sibling items keeps them at the same indentation level rather than increasing it.
