Thanks for the screenshot. Let me discuss this issue with our hardware team to see if they can provide further feedback here regarding this behavior, once I hear back I or another Roon support staff member will reach out again.
The first time a Bluesound zone has been discovered by Roon it will inherit the existing BluOS zone name. After this, you can change the zone name in Roon by clicking on the “pencil” icon next to the “Jacsis Office” text in the Settings > Audio screen.
