I have 3 Amazon Echo devices in my home, all of which individually appear in Spotify Connect. I set up a few groups through the Alexa app, one that includes all three Echos, and two more containing different combinations. However Spotify Connect will only display one group at a time.

Above, only the Everywhere group containing all three Echos appears in Spotify Connect. If I switch to that group it's still the only group that appears:

If I ask Alexa to switch Spotify to one of the unlisted groups, she can do that, and then only that group will appear:

Is there a reason Spotify Connect will only display one speaker group at a time? I know the other groups work, as Alexa can utilize them to playback Spotify content. Is this an issue with Spotify Connect? Or is Amazon somehow to blame?
