IP22 12-30 Re Bulk Setting

I have set the rebulk to every 7 days but while it is in storage mode at 13.5V it never re bulks back to 14.6v where it is set so it will top balance every 7 days? 200 AH LiFePO4 battery in boat as house battery, loads typical during week days virtually 0 (0.10Amps) ? Any ideas or more info needed from me?
