Employee Bi-weekly contribution amount not calculating when setting up open enrollment

When enrolling into the FSA Healthcare option, when selecting the amount of coverage, the employee Biweekly Cost does calculate and remains at a balance of $0.00 until you fully submit your benefit enrollment. After you have submitted it and you view your enrollments, only then does it display the Employee Biweekly cost.

This has always been an issue and has never worked in classic/responsive UI and still does not work after converting to redwood pages.
