Within the advanced partitioning dialog, there is a button called 'update settings' which is available after changes have been made. In the German translation this is described as 'Aktualisierungseinstellungen' which means something completely different. I would suggest to translate it with 'Änderungen übernehmen' or 'Einstellungen aktualisieren'.
Thank you for reporting this mistranslation. I did change the string to "'Änderungen übernehmen". Thank you, Roman
