Rails I18n validation deprecation warning, after setting enforce_available_locales = true

You placed something like this in config/application.rb

I18n.enforce_available_locales = true                                        
config.i18n.load_path += Dir[Rails.root.join('config/locales/', '*.{rb,yml}').to_s]
config.i18n.available_locales = ['es-LA', :en]                               
config.i18n.default_locale = 'es-LA'

And the warning still appears:

[deprecated] I18n.enforce_available_locales will default to true in the future.
