Duplicating pages Issue

Hi, i’m new to creating websites, so apologise in advanced for my stupid questions but I could not find the answer.

I’m creating an agency type of site which entiales me creating different profiles for clients to view. I’ve created the first profile how I want it, so I wanted to duplicate that page so all I need to do is change the page name and the details of the person on that profile.

When i duplicated a page to create another profile, it also changed the details of the original profile.

When i enter quick edit, these are the settings….however I don’t know how to set each profile up so they only edit themselves and not the original page.

The parent: main page (no parent)

Template: page no title

ANy help would be much appreaciated.
