Niklas04 thank you for the update. Keep me posted if any other issues.
We are interested in collaborations with other folks. The translation was always on our radar, however, we never prioritized it due to a massive amount of functionality that needed maintenance and documentation.
Within the next few AAM updates, we are going to clean-up AAM UI labels and will ask the WordPress community for help to translate AAM.
Appreciate your interest in AAM and help.
