Problems with the checkmark "Check for already exported content" for exports

[schluchzi]

Hi,
I am using TYPO3 version 11.5.30 without any additional extensions. I have installed the Localization Manager in version 11.1.0.
I am trying to translate our website with the Localization Manager. For an initial translation, this would also work. But if I have already translated content, or content that I have already exported and re-imported, then it is exported again each time. I have set the checkmark "Check for already exported content" during export, but nevertheless all data is ALWAYS exported. Is this a bug or is this function not implemented in the extension? Or am I missing a setting somewhere that is responsible for this?

With kind regards
Luca
