Images not synched for non-default language

Hi everybody
I have a multilanguage site with a team page. I would like to only upload the images of the team members once for the main language.
Below you can see the blueprint, with translate: false for the image-field.
However, the images are not shown on the second language page, neither in the panel, nor on the site.
What am I doing wrong?
Thanks a lot for your help!

team:
    label: Team
    type: structure
    style: table
    fields:
      name:
        label: Name
        type: text
      ... other fields ...
      bild:
        translate: false
        label: Bild
        type: files
        uploads: image
        max: 1

team.de.txt:

Team:

- 
  name: Astro Galore
  bild:
    - file://YRoEPDL4XnvNFggd
 ... other fields

team.fr.txt:

Team:

- 
  name: Astro Galore
  bild: [ ]
 ... other fields

The translate option doesn’t work on the subfield level of a structure field, but only on the main field itself. There is no inherent relation between the items of a structure field.

Thanks @texnixe ! I was totally convinced I had built it that way.
