Kontact Lists

I cleaned all my addresses out of Kontact and then imported the Family group 
that I exported from my Ubuntu Evolution. I exported them as a .vcf file. 
Imported to Kontact file that I created "Family address book" in the lower 
panel that is called Address Books. I cleaned it up a little and liked it. I 
proceeded to export and then create a file called Business. When I highlighted 
the Business file it had my Family address book in it also. Every file I created 
to be a different category had the Family address book. I tried to import a 
small file and they merged . Evidentially I am doing something wrong when I try 
to create a separate category.
I am using Kontact 4.3.4 in Mepis. Is there a conflict or is it my brain.
Thanks for any help.
