For my upcoming flight in 3 days, no upgrades have processed and 12/12 seats are available in F

Yeah sometimes the RM OU/OY algorithms make no sense. I applied a RUC to a ATL-HNL and HNL-ATL flight I’m taking in a few weeks and my outbound cleared about a week after I applied it and there were only 15 seats left at the time it cleared, yet my return still hasn’t cleared even though there are 24 seats left and I’m flying back on a midweek Wednesday flight?

Also since I booked the return flight, the # of available seats in D1 has only increased from 21 to 24.
