"You don't have access to this booking page" ERROR

I created eleven (11) Microsoft Bookings pages that my employees use to schedule appointments with customers.  We have had intermittent issues with Bookings here and there over the last year. But they either fixed themselves or we just reloaded the employee (or moved them to an incognito browser) & that seemed to fixed the issue. However, access to the "internal admin pages" (i.e. where you add employees, change settings, etc.) for 2 of my Bookings pages "disappeared" more than 10 days ago from everyone's Bookings main screens. The Bookings pages still exist on our company network because when I search for them, I can find them. However, when you click on them, you receive an error message stating, "You don't have access to this bookings page". I am the Admin and creator of all our Bookings pages. I have "Administrator" rights for each page. However, I am not a "Super Administrator" within my company's network, so I am only able to see Bookings sites created within our network that I created. 

I can access all nine (9) of the other Bookings pages.  There are no issues with them.  I also cleared my Cache and tried to access the pages in Incognito mode and tried an alternative browser.

What is also strange is when I first accessed the Bookings Admin page, both of the pages were on it. However, within 3-4 seconds, they deleted themselves.

How do we fix this and get access to these pages? I do not want to have to recreate these pages. Additionally, we have customers already loaded into the inaccessible Bookings page and need to access them. Help, please!
