Catch 22- facebook page name

Good morning -

I am the admin for 2 health care clinics that now operate under the same name.

On facebook, the pages are named based on the locations: Random Clinic 1, and Random Clinic 2. I have created a parent page "Random Clinic". I am trying to migrate Random Clinics 1 and 2 as locations of Random Clinic.

However, I keep getting the error message that I can't add pages that have a different name as locations.

When I try to change one of the clinic's name to Random Clinic I get this prompt: "It looks like you already manage a Page named Random Clinic. Please choose a different name or go to your current Page."

How can I get around this?

Thanks for your help!
