Wrong hostname displayed at Remote Login screen in Share of System preference

I used sshd service for ssh connection in macOS Monterey 12.6.

Today, I found that hostname of guidance meesage in Share > Remote Login different with real hostname.

Real hostname is like below.

But the guidance message of remote login window displayed like below image.

That wrong displayed hostname's device is my colleague's device.

I want to know why it happen and how to fix this.

Please, guid me if you have a resolve way.

Thanks.
