I18n not working

I am trying to use i18n with Netlify CMS and Next JS to publish blog posts in different languages. However, the settings in my config.yml are ignored in the cms admin page e.g. I do not see the internationalization options but only the blogpost widget for one language.

The repo is here: https://github.com/jakobkolb/lizu-homepage

This is the relevant content of my config.yml

backend:
  name: git-gateway
local_backend: true
media_folder: public/img
public_folder: img

i18n:
  structure: single_file
  locales: [en, de]
  default_locale: de

collections:
  - label: "Blog"
    name: "blog"
    folder: "content/blog"
    create: true
    i18n: true
    format: "json"
    fields:
      - { label: "Title", name: "title", widget: "string", i18n: true }
      - { label: "Publish Date", name: "date", widget: "date", i18n: duplicate }
      - { label: "Featured Image", name: "thumbnail", widget: "image", i18n: duplicate }
      - { label: "Body", name: "body", widget: "markdown", i18n: true}

Any help is greatly appreciated!
