Hi, I have a problem Only RGB lights up, but cold and warm doesn't light up Any way to fix this?

Maybe flag 9: Code: text Expand Select all Copy to clipboard 9 Use separate RGB/CW modes instead of writing all 5 values as RGB can you try?

I’ll try that once i get home, I haven’t try that flag since the RGB and CW controls are already separate
