Group of Sengled bulbs

I have several groups of sengled zigbee bulbs which are dimmable but not white or color tunable. However when using the group/scene app to group them together, the option to tune the color is there. Is there a way to disable this?

First thing that comes to mind is if you have the right driver chosen for the bulb? Perhaps it's something that's there, but since it's not supported by the bulb probably won't affect anything. I'll be checking this when I get home. My vpn is off, so I can't connect. So frustrating when I accidentally do that.

No way to change this currently. It shouldn’t cause any issues that I’m aware of, but I only have the RGBW lights. Do you have the lights selected as dimmers in the group app?
