waiver: HSA with age banded customization with no contingent eligibility ER coverage issue for election changes

I have verified this issue and consider below scenarios:
Customization: Flex Plan with no contingency
Cost coverage setting:Age Wise Coverage? ER coverage: 120

Add new employee with effective date 01/01/2017 : He got 120 ER coverage
waived plan with effective date 05/01/2017 it will show 40 ER coverage on Enroll now screen
again enrolled in to the plan with same effective date 05/01/2017 employee got ER coverage 120

one more difference is found on View enrollment screen and confirmation statement it showing ER coverage 40

Failed scenario
