Spotify duo see the same home speakers as account managers

We have Spotify Duo, and I can't seem to find the same home speakers as my partner. We have an Alexa upstairs and downstairs, however, if I want to use them they don't appear in my Spotify connect. Would it be possible for the speakers seen by the managers account to be seen by the other partner in the duo plan? Is this a limitation on the Alexa devices only being able to have one account linked or is it something that can be fixed by a software update via the Spotify app?
