Not sure but for me all my bulbs and Z flashes red then white however for me they never stop doing that, it just goes on until I set a new scene then it stops.
Even turning the light on and off does not fix the issue.
Do you have your groups setup as rooms or do you have your location setup as rooms?
When I first used LIFX, I had it setup like this:
Location -> Group -> Light
Living Room -> TV Area -> TV Left
After talking to LIFX support, I found out this was not the correct configuration. If this is what you have setup, that’s your issue. If not, I think you should contact LIFX support as they’ll be able to help you more past this point.
