It says it is going back to replenish. It doesn't need to, but sometimes something gets confused. Clear the patrol zones and tell it to return to Pago Pago. Then reset your patrol zones.
Just to elaborate on what Dan said, if you set the patrol zone while the ships had a home port of, say, Pearl Harbour, and then switched the home port to Pago Pago, the patrol data would still think it had to return to PH. Not sure if it does a recheck when it actually does end the patrol, but I think not. Therefore the DDs could need to replenish fuel because of the round trip PZ-PH-PZ, but the screen info fuel check says there is enough fuel to go PZ-PP-PP so it is still green.
But my first guess is the ammo replenishment. Unless you have an AE or AKE at Pago-Pago, it may not be able to replenish the carrier or cruiser.
