Messed up my HOME page in 2024 theme

Hi all,

I just installed WP for a friend of mine at this link (https://kleokon-hortikultura.com/home/) and am having some probably very basic issues.

1. I don’t know which page is currently set as the Homepage (in the “Reading” section of Settings it says “Your latest posts” (?);
2. The HOME page, under the header menu link HOME is messed up – the code is showing instead of formatted well, page ??

Any ideas what I am missing here? Many thanks!

The page I need help with: [log in to see the link]
