Google Assistant only recognize one of many devices from HA

I configured the google assistant component the manual way by adding a google action. All devices exposed through the configuration are showing up correctly and I can control them all through the Google Home App in my phones/tablet. But my Google Home Mini (and Google Assistant on the phone) only recognize one of all the devices by name.

I tried re-syncing the devices, adding multiple aliases for the devices, rebooted the Google Home Mini several times and I even re-created the action. It’s always the same device that work.

Not sure if this is on the Google side or Home Assistant side so I thought I’d ask here if anyone had a similar problem?
