Contacts won't let me add a new contact

in contacts every time or way I try to add a new contact the compute jumps to and existing one.

I tried 2 ways from within Contacts. First: with "All contacts" highlighted, clicked on the "+" at bottom right, selected "new contact", blank card came up, entered last name, then either tabbed to "first name" or just clicked on "first name", start to enter a name, BUT then the window popped to an existing contact, and I am out of the protocol for adding a contact. Second I tried by starting from the menu bar-file-newcard but Contacts again popped me out of the process for adding a contact.

Macbook Pro M1, Ventura, recent update.

Help would be really appreciated.
