Hello.
I woluld lije to have any advice about this matter.

Please read the problem carefully before answering, because it only happens to me on one translated page, and not on the rest, using exactly the same configuration as on the three previous ones.

Look, the quickest example you can see is on the next page, although it happens on all the blog news pages and News we have in the Spanish translation.

If you go to https://sierrablancaestates.com/luxury-conscious-living-sierra-blanca-estates-commitment-to-the-sustainability-of-true-luxury-through-its-projects-villa-sierra-blanca-and-karl-lagerfeld-villas-marbella/

You will see that on the right side the Foundation’s banner is displayed below the one above it and then it remains fixed.

The same thing happens, and it does the same on the French translation page (https://sierrablancaestates.com/fr/vie-consciente-du-luxe-lengagement-de-sierra-blanca-estates-envers-la-durabilite-du-vrai-luxe-a-travers-ses-projets-villa-sierra-blanca-et-karl-lagerfeld-villas-marbella/) and on the Polish translation page (https://sierrablancaestates.com/pl/luksusowe-swiadome-zycie-zaangazowanie-sierra-blanca-estates-w-zrownowazony-rozwoj-prawdziwego-luksusu-poprzez-swoje-projekty-villa-sierra-blanca-i-karl-lagerfeld-villas-marbella/).

However, in the Spanish pages (https://sierrablancaestates.com/es/luxury-conscious-living-la-apuesta-de-sierra-blanca-estates-por-la-sostenibilidad-del-lujo-verdadero-a-traves-de-sus-proyectos-villa-sierra-blanca-y-karl-lagerfeld-villas-marbella/)

you will see that the banner appears covering the one above it, and then it stays fixed as it should, but its configuration in all the translations is the same

I don’t understand where the error can be because the configuration in all the elements is the same, and the error is only in the Spanish page.
