Is this a 20D Issue - Participant not able to proceed with Enrollment from a Life Event created by B

Summary

Participant not able to proceed with Enrollment from a Life Event created by Benefits Admin in Benefits Service Center

Content

In the Test environment (EDBZ-Test) which was upgraded to 20D, when Benefits Admin created and evaluated a life event in Benefits Service Center, the enrollment is not available in ESS (Continue button is greyed out) although the life event is in "Enrollment Window Started" status.
From the Benefits Service Center, the Enroll button is enabled and the Admin is able to perform enrollment. Suspects this to be an issue in 20D as the problem is not present in Production EDBZ and EDCA-Test environments which are in 20C release.
