I have the Seattle Avionics maps subscription.

On my 5800, the airport diagrams for KSJC and KPAO (possibly other airports as well) are stuck on a 2018 version of the plate. I have verified that the airport diagrams on the USB stick are current. I even reformatted the USB stick, and populated it again from scratch to make sure there are only new airport diagrams there. Despite these efforts, the 5800 still displays the old diagrams.

Are the diagrams somehow stored on the internal storage? How can I fix this?

Thanks for any insight.
