Seniority dates - Calculating random dates

Summary:

Hi,

We have implemented Version 3 of Seniority dates for our client and as a part of implementation original hire date is configured which use to fetch initial hire date of employee or contractor and it should not change when there is any Global transfer or rehires etc.

We have created a fast formula to fetch the original start dates of employee or contingent worker from value set (MHI_EMPLOYEE_ORG_HIRE_DATE_VS) and print the same in seniroity dates page but when we ran the Calculate Seniority date process to calculate orginal hire date for all the employee then it calculates random dates for few employee like 1971, 1900, 2500 etc.
