bufferline.nvim does not configure with packer.nvim

Question

I want bufferline.nvim configured such that the buffers get offset when nvim-tree gets expanded. However, configuring it with the documentation didn't have any effect.

Some more testing revealed that none of the options were taking effect. See MRE below. Most noticeably, the separator style remains default.

init.lua

require("user.plugins")

vim.g.loaded_netrw = 1
vim.g.loaded_netrwPlugin = 1

require("nvim-tree").setup({
    view = {
        adaptive_size = true
    }
})

vim.keymap.set('n', '<c-n>', ':NvimTreeFindFileToggle<CR>')

vim.opt.termguicolors = true

require("bufferline").setup({
  options = {
    separator_style = {"AAAA", "AAAA"},
    hover = {
      enabled = true,
      delay = 200,
      reveal = {"close"}
    },
    offsets = {
      {
        filetype = "NvimTree",
        text = "File Explorer",
        highlight = "Directory",
        separator = true
      }
    }
  }
})

    if fn.empty(fn.glob(install_path)) > 0 then
      fn.system({'git', 'clone', '--depth', '1', 'https://github.com/wbthomason/packer.nvim', install_path})
      vim.cmd [[packadd packer.nvim]]
      return true
    end
    return false
  end
  
  local packer_bootstrap = ensure_packer()
  
  return require('packer').startup(function(use)
    use 'wbthomason/packer.nvim'
    -- My plugins here
    use 'nvim-tree/nvim-tree.lua'
    use 'nvim-tree/nvim-web-devicons'
    use 'akinsho/bufferline.nvim'
  
    -- Automatically set up your configuration after cloning packer.nvim
    -- Put this at the end after all plugins
    if packer_bootstrap then
      require('packer').sync()
    end
  end)

Solved: The configurations were being overridden by a different extension barbar which, despite being removed for the MRE, was cached at ~/.local/share/nvim. The configured options are taking effect after deleting the cache.
