Maintain Designee Eligibility not end dating coverage at the end of the month

Hello,

We would like to end medical coverage for dependents at the end of their birth month. We are on 11.5.10.2. We do not want the life event to automatically fire. We just want the coverage to end at the end of the month.

We have the following set up to achieve our goal however, the coverage is ending 1 day before the dependents birthday instead of the last day of the dependents birth month.

1.            Program Enrollment Requirements > Dependent Coverage > Plan Type

                Dependent Coverage Start Date is set to As of Event Date

                Dependent Coverage End Date is set to One Day Before Event
