RGBWWCW Flood light and Scenes

Can anybody help me this has been driving me bonkers for ages now. I have a novostella 30w floodlight which has been Tasmota’d ver 7.00 firmware. It’s an rgb flood with cool white and warm white leds. All works fine. I can set the colours rgb or the warm white or cool white leds within home assistant. The problem I have is with scenes. If I try and set a warm white or cool white scene and save it. When I go to recall it again I get a combination of the rgb lights making up the colour instead of the CW or WW leds. Any ideas
Thank you.
