Describe a bug.

Steps to reproduce:

1. Follow your tutorial on 18n to translate block tunes
2. Realize it does not work

Other translations from the tutorial work well

the version I use is 2.20.2

...
      blockTunes: {
        "delete": {
          "Delete": "Удалить"
        },
        "moveUp": {
          "Move up": "Переместить вверх"
        },
        "moveDown": {
          "Move down": "Переместить вниз"
        }
      },
...

Expected behavior: it works
