Translation errors in German

Some strings are not correctly translated to german. Here are some examples I found:

• Roles -> “Update role” button is translated to “Rolle l?schen” (which means delete role), should be “Rolle aktualisieren”
• Role capabilities -> “Editing” is translated to “Hindern sie Prüfer daran, die Revisionen anderer zu bearbeiten”, should be “Bearbeiten”
• Role capabilities -> “Deletion” is “Rolle l?schen”, should be “L?schen”
• and then a lot of just untranslated content
