Different color in night mode

I’ve purchased two wifi bedside lamps, all is ok but when I select night mode, and set the maximum brightness one is more yellowish and more intense than the other one, both are in the same group. Some fix? thx

Which version of firmware of the two lamps? Are they the same?

yes the same latest firmware

same problem to me with 3 bedside 2 :))
I have 3 lamp and in night mode all 3 are different “color”
