Discovering Sonos finds too many devices


I’m new to Smartthings. Just got my hub and started setup. When it goes out to find devices, it detects my Play:3 and Play:5 just fine, but for the Lounge I’ve got a Playbar, Sub & 2x Play:1s grouped together. Smartthings finds 3 things called ‘Lounge’. One of them says ‘Stopped’ which appears to be the right one, but the other two say ‘0’ (zero) and when clicked show a play button which doesn’t do anything.

Initially, I just deleted them both, but everytime I try to add a new device, they come back.

Any ideas?
