There is an issue that if you ungroup a DS and then re-start the un-grouped one from the current track showing it re-groups the zones.
When you ungroup a DS and look at its current track it shows the last track that was playing from the group. This is not a track in that DS playlist. If you re-start the track it re-groups all the zones.
You can see what i mean in the video link.
