Don't know what it was, but I completely removed CB and all db table entries, reinstalled CB and Subs and Conditional plug. It all seems to work now as I want it to. Haven't implemented gateway yet, but at least I'm getting free subscriptions using a drop down selection field and conditional availability of the plans associated with that drop down field selection. I'll let you know if I figure out what was causing the problem or if it comes back with further config.
