[Cerrado] Automatic translation

Background of the issue:
I translated the website using automatic translation like I did multiple times before with other websites. The default language is Croatian, and I have removed the language switcher. The English version can be accessed at enlace oculto.

Symptoms:
When I go to the English version (translated version), everything looks broken, especially the header section. This is visible in the screenshot: enlace oculto.

Questions:
Why does the English version of my site look broken after automatic translation?
How can I fix the layout issues in the translated version of my site?
