I resolved this issue by deleting four keys in my options table (wp_84ikeq_options) – fbcj-members, fbcj-groups, fbcj_member_label, & fbcj_group_label, then reinstalling and reactivating the plugin.
The key to setting this up properly is to create the profile field first, then turn on the members option, hit save, fill in textfield with name of profile field, then save again.
