I'm reviewing our most recent readiness report (created today!) and noticed that Lightning hasn't struck yet for case teams or case contact roles.  The readiness report shows that these items are included in many profiles, yet when I search through my profiles I can't find them.  Also, the related lists for these items aren't on our case page layouts, in fact we haven't set up case teams or case contact roles at all.  If these aren't set up yet, how can they be included in so many profiles?
