Setting Octopress

I've installed and configured Octopress as described at:

• Initial setup
• Basic Configuration

Installing octopress-multilingual

Then I've installed:

group :jekyll_plugins do
  gem 'octopress-multilingual'
end

and I've run:

$ bundle

Setting octopress-multilingual

Finally I've been following the Indexes section but there are unexpected behaviours:

• at http://localhost:4000/index.html
  • there are all posts in all languages in content area (that's right)
  • there are all posts in all languages in recent post aside area (that's right)
• at http://localhost:4000/index-it.html
  • there are not any posts in content area (that's wrong)
  • there are all it posts in recent post aside area (that's right)
• at http://localhost:4000/en/index.html
  • there are not any posts in content area (that's wrong)
  • there are all en posts in recent post aside area (that's right)

Thanks,
