Previewing/Editing Different Pages of a "Restaurant Menu"

Site URL: https://coral-dachshund-f48p.squarespace.com/products

I'm creating a page with a Restaurant-style Menu and need some help.

For the menu I have total of 4 pages.  I have added contents to all 4
I am able to see the first page but I can not preview how the other pages (pages 2-4) look

I have saved my work and gone into preview mode.  But each time I click on the different menu pages, it will show the page for 1 second and then go into "Edit page" mode and will only show page 1 on the edit page.

How can I preview the other pages?
Is it possible to show the different pages while I'm editing so I can edit and preview at the same time?

Thank you
