iPad Air name mismatch in Apple Account

Please explain this inconsistency and how I might fix it. I asked about this before, but perhaps I explained it in a confusing manner.

I just got a new iPad Air and transferred everything over from an iPad Mini 7 (named Minipad7) I have and which I did not delete. The iPad Air got automatically named "Minipad7 (2)". I immediately renamed it "AirPad", which shows up, as pictured below in Settings/General/About on the iPad Air.

However, in Settings/[my name]/Apple Account the iPad Air is still showing as "Minipad7 (2)", as shown in the second screen capture.

Why is this the case and how can I fix it?

I checked in the iCloud.com website on my Mac and find that the device is properly named there, both in the device list and Find My.
