HI Rosa,
Typically when you copy an event, you can choose which features you'd like to keep in the new event and the design elements should transfer over as well. If you've saved your header within the media library, you can pull this in to the German event and all of the default content should be automatically translated. However, you would need to update any custom content that is on the site to German, as the system won't do that automatically. To customize the content, you can go to Marketing> Language Management.
Thank you!
