Text Message Forwarding

I'm trying to let my phone forward my message to my new mac(m1 chip), however, after the setting up there seems to be two replicated device names both for my new mac in the forwarding device list, is there any way to delete one name from my list? Is this happening because I tried the migration assistant two times? There is a similar question asked in 2014, from that question, the solution is to change the password, but I hope there's an easier solution, changing the Apple ID password is inconvenient, which you can see in the following picture, one is open, one is closed, but they are the same device? (there is also one issue, if I only open the created device name (close one), I can't receive the message in my mac from the iPhone, or if my Apple ID is stolen by others?)
