a scenario in the Benefits module where I need some clarification

I have a scenario in the Benefits module where I need some clarification:

An employee has already enrolled in a medical plan and added parents (father and mother) as dependents. Now the employee is getting married, and a Marriage life event is triggered successfully.

However, during the life event, the existing medical plan is not showing up, so the employee is unable to add the spouse as a new dependent under the same plan.

My expectation is that during this new life event, the existing policy should be visible, and the employee should be able to edit the enrollment to include the spouse along with the existing dependents.
