Hello,
Thank you for reaching out, and we apologize for the inconvenience caused by the incorrect German translations in SP Page Builder.
To reset the language back to English, please follow these steps:
Navigate to Extensions → Manage → Manage in your Joomla administrator panel.
In the search field, look for SP Page Builder (de-DE).
Select the extension and uninstall it.
Once the German language package is removed, SP Page Builder will automatically revert to English as the default language.
Kind regards
