Cohort Analysis - report does not make sense

 The Cohort Analysis report, displayed for 12 weeks, shows two weeks that had 0 sessions in their Week 0 (I'm interpreting this as nobody responded to the campaign in those two weeks).  But then, over to the right, those weeks show quite a few sessions in later weeks, the 6th week for one of the two weeks and the 8th week for the other.  How can this be?  If there were 0 sessions to start with in Week 0, then there was nobody in that week's cohort so there should be nobody to make a return visit 6 or 8 weeks later.  What am I missing?


My cohort report metric is Sessions.  The cohort is based on a custom segment of sessions with vendorxyz as the Source. 


How should I be interpreting this?
