Benefits Administration Fluid Statements Functionality - Suppress prior Statements on Summary

We are going live with the Fluid Benefit Statements. We noticed that there appears to be Enrollment Preview Statements which are available prior to us going live with any Benefit Statements. We have tried to change the effective date on the Benefit Statement Options in hopes that would suppress Statements which were created prior to the effective date we defined and if the Self Service checkbox was de-selected. That didnt work. Does anyone know how to suppress these Statements for events that pre-date us going live?
