Heading should say 2 x Sonos One speakers not (play)

I have 3 x Sonos One speakers (gen 1).  One set up in dining room and 2 paired as sterio in lounge.   I have successfully connected the Sonos roam to a Bluetooth turntable and I inturn grouped in to the rest of the system however the audio while it comes out of the roam and the dinning room speaker it only comes out of one of the stereo paired speakers in the lounge.   If not using Bluetooth and just connecting Roam to my whole system all music comes out all speakers as normal.  Does the roam not support Sterio on already paired speakers in the system when in Bluetooth mode?
