Kontact - can't delete resource's address book

Hi guys,
I have some address books (friends, work, etc), and I want to delete the “resource” book, but every time I reopen contact, it re-appears.
Any ideas how to resolve this issue?

You cannot delete the resource’s address book because Kontact will always recreate it; you can only import the addresses from your other address lists; there are several possible filters you can use.

OK, I though than on previous versions, I could have 3 resource’s address book, and nothing named “resource’s”.

I don’t know how ‘previous’ that is; that was my experience when trying to solve a different problem a year or so ago.
