Adding new contacts/dependents not allowing Family Option

Summary:

We have the eligibility that If Employee has no dependents , Employee will see only 1 option "Employee Only" .If Employee has Spouse (Employee will have Employee Only, and Employee +1 ) Option,

So During Open If an Employee with no contacts adds Spouse and children , Employee should see all the 3 Options (Employee Only, Employee +1, Employee+Family)

However Employee is still seeing only Employee Only option to Enroll , even after adding the Contacts ,during Open.

Requirement is Employee Should also see Employee+1 , if employee adds Spouse or Child and Employee+Family , if Employee adds 2 or more dependents.

However System is not working as Expected.
