Hi @jansky15
Thanks for reaching out.
It is expected that when you set a static page to be the homepage of your site, WordPress hides it from the URL. It is also expected that when you check your homepage slug from the Quick Edit
option or if you use the block editor, you will still see the slug of the homepage.
So whatever you set as the slug for your homepage will reflect that, but when it loads for a user, it will just appear without the slug or just as your top-level domain name. In that sense, we can say slug remains hidden, so we don’t treat this as an issue of concern.
We recommend that you check out the following article if you want to optimize your homepage: How to optimize your homepage.
