Hello,
As I can see, you have installed the animals demo version. I’ve edited the banner-home-page on your site. Please check.
If you want to set this page as Home, go to Dashboard > Settings > Reading > Your homepage displays > select the page.
Do you want to apply this header https://gyazo.com/777d117e1da32608ac26fbe739e672cb for the Home banners page only?
Regards
