Benefits Fast Formula Person Change Causes Life Event not working

Requirement is to add a Life Event as soon as employee is terminated with specific termination actions and rehired next day as a retiree.

We have created a Person Change Causes Life Event fast formula and attached it to Person Data Change and have attached that to Life Event Data Change.

To get the Termination Action we have created a value set to retrieve termination action based on action occurrence id.

The fast formula is not working and I am not able to find any method to debug this fast formula.

Could anyone please let me know what am I going wrong.
