Grade Step Progression is Returning Ineligible as Eligible

Summary:

Grade Step Progression is Returning Ineligible as Eligible

We are using Fast formula to fetch this eligibility, as per formula it is working as expected, But in some cases like for few employees system showing as eligible even though employee is returned as ineligible from formula.

Please suggest how to fix this issue, SR raise for this, I was asked to ask this question in community to get fix.

For Example: As we see in the log, for the employee who is not eligible for that particular employee Fast formula is returning ineligible Which is expected. But empoyee is returning as eligible.
