POIs - Paylines are not created for those Termed w Pay but for Retired w Pay

We have some POIs in our system who we generate pay data for.  This doesn't make sense to me but wondering if someone else knows.  Basically we have POIs all within the same paygroup and I am finding that those with a Termed w Pay status are not having paylines created when we sheet.  hose who have Retired w Pay statuses are.  I changed a user who didn't have a payline created from Termed w Pay to Retired w Pay and when running the calc they had a payline created. 

I always thought that the Payroll/Employee Statuses of "w/ Pay" allowed us to have them included in the payroll process.  I checked the Action Reason setup and they status truly is w Pay.  Not sure if there is a nuance to POIs compared to EMPs.
