Create New Orbweaver Profile by Modifying existing one?

I must be doing something wrong. I want to create a new profile for my orbweaver that starts with a subset of an existing one. What I am trying to do is to create a subset of an existing profile. When I create the keyset, and try to import the existing one (or a copy of it), it makes a copy of the first keyset., and reverts to the first keyset. Keyset 2 remains blank. ANy ideas? Thanks
