Eligibility hours issue in 2018

Client has a Time Off Code setup with a Rate Table.  Rate changes on 36 and 120 months.  Has "12" in the Eligibility HOURS field.
Employee shows eligibility date of 02/28/2009 but still showing pre 120 rate.  I have to change it back to 02/28/2008 to make it change.  Appears to be using Eligibility hours in calculation.

On 2017, setup the Benefit code the same way, changed Hire Date to 02/28/2009 and it shows the 120+ rate.  I'm thinking this is correct - the Eligibility Hours should only affect the start of accrual - should not affect the date at which the accrual rate changes.

Any opinions?
