I must have some other plugin or setting not set correctly. Under the CB Lists tab if I try to add a row the only fields I can see from CBSubs are the invoice data: cb_subs_inv_first_name, etc., nothing related to the plan. I do have some of the CB-Subs plugins not published but they all do not appear to be related to the plans, (like google analytics, email, tax, url) perhaps one of those is required.
