'TYPO3 language handling: Problems with free mode when fallbackType=fallback

This is my language configuration for my TYPO3 v10 site in site configuration:

fallbackType: fallback
fallbacks: '0'

This works as expected for pages in "Connected Mode". But when an editor creates a page in "Free Mode", the translated page displays in FE both the translated and the default content elements. I do not understand why the content elements from default language are shown here. Is this a bug of TYPO3?



Solution 1:[1]

This is a TYPO3 bug: https://forge.typo3.org/issues/90261

There's an extension which fixes this: https://github.com/qbus-agentur/typo3-dynamic-language-mode

Solution 2:[2]

I would consider this a bug. Probably related to https://forge.typo3.org/issues/88965#change-442588 (please add a comment there to bring more focus on this)

But some things should be clearified here anyway:
