Incorrect Mac OS Computer Device Names

Our Mac Studio has the name “Name1” on the Desktop [1]: 

Under Apple Menu > System Settings > General > Local hostname it is named “Name1.local” [2]: 

Yet under Apple Menu > System Settings > Apple Account > Devices it is named “Name2” (but with the correct computer model, a Mac Studio, listed directly under the incorrect name) [3]: 

How do I change the Devices name from Name2 to Name1?

Sorry for what is likely an ignorant question, but we had a major crash/restore on our MacBook Pro 14” and I’m into a week of trying to dig out from that :(

OS Sequoia 15.2

Thank you!

PS I Photoshopped the actual names to Name1 and Name2 for privacy, but you get the idea.

PPS I searched Perplexity for an answer [4]: 

But this doesn’t seem correct cuz there is no Apple Menu > System Settings > Sharing menu that I can find [5]: 

PPPS: Interestingly, under Apple Menu > System Settings > Apple Account I also see listed under the Mac Studio our now normally functioning MBP computer (a MacBook Pro 14”) with the text “(3)” appended to the otherwise correct name [6]: 

So, in other words, I’m asking how I can change names so that (in the last screen image) Name2 changes to Name1 for the Mac Studio, and Name2 (3) changes to Name2 for the MacBook Pro 14”
