Hello, Lorna,
Thank you for getting in touch with us.
Please read this article https://xstore.helpscoutdocs.com/article/139-cant-see-changes-in-the-header-on-the-home-page
Your Home page uses a custom Header, so you need to edit it via Multiple headers.
Your changes for the Default header are visible on all other pages, for example, check the Shop page.
We hope this information is helpful.
Kind Regards, 8theme team
