Multi-language Kirby site loses it structure entries inside a Block, when translate:flase is applied

[AlexanderBoenninger]

Description

In a multilanguage page, the files in a files field, that is nested in a structure field get lost for the second language, when saving the page. The structure field is set to translate: false.

Expected behavior
I expect the files to stay there, since the translate: false should cause, that the entries are not touched for the sec. language.

To reproduce

1. I have e.g. 2 languages and a structure field inside a Block with files (not sure if it matters). The structure field is translate: false
2. I fill it with entries files and other information.
3. Switch to the next language. Enter content. The structure field is still filled and not editable (as expected).
4. save the page.
5. Structure field is empty.

Setup
Kirby Version
"name": "getkirby/cms",
"version": "4.6.1",

Console output
no output

Additional context
I use the kirby translator from @johannschopplich and thought i might be a bug in the plugin, but it was not:

I can't reproduce the issue with just structure field. Do you mean structure field in blocks field? Could you share you full blueprint file please?

[AlexanderBoenninger]

AH Yes it seems to be necessary that it is in a block!
Thanks.

@AlexanderBoenninger Would be really great if you could provide us your blueprint - really helps us in replicating the issue instead of guessing around. Thank you.
