CMS says Item Exists

I have a CMS called Sub-Categories
I am trying to create a sub category called “Payroll” when I try to create is names the slug - “Payroll-2” as it says payroll already exists.
Please see images below - but payroll is not an item that is listed.

Option 1 - I need to know how to bring back a deleted CMS item
Option 2 - what am I missing?

This has been resolved - not sure how to delete post
