Only the i18n translation only shows: 1 item left

Only the i18n translation `only shows: 1 item left`. When I test in the console the translation works fine:
```ruby
irb(main):001:0> I18n.t('footer.todo_count', count: 1)
=> "1 item left"
irb(main):002:0> I18n.t('footer.todo_count', count: 0)
=> "Nothing left"
irb(main):003:0> I18n.t('footer.todo_count', count: 3)
=> "3 items left"
```
