Music assistant not showing players - SOLVED

I’m not sure if we can ask questions about MA on here yet as it’s only recently been bundled in.
I am running HA 2024.12.5 on Docker. I have four Bose Soundtouch speakers which show up correctly on HA in the devices and I can manage them (volume, settings, etc) from HA.
I am now using MA and have added loads of music but these speakers do not show up in the players section of MA so I can’t select them to play music.
In addition, the players are showing in MA ->Settings → HA media players → Generic settings
Is there somewhere else I need to add speakers to make them show up in MA?
Many thanks
Mike

As is typical, I have answered this myself!
I removed the players from MA ->Settings → HA media players → Generic settings
Saved
Added the speakers back
Saved
Now they show!
