I hope you have made some progress on this issue.  However, the 'Choose field to group by' option for the Kaplan-Meier Estimate does not work unless the field you have chosen to group by is the FIRST field in your dataset.  So, putting a Select tool before the Survival tool, and moving the 'group by' field to the top of the list solved it for me.  I hope this is helpful to you, too.
