Yeelight bulb color 1s faulty green color

Hi

Lately I’ve been having some issues with the green color of my lamp, when I turn it off using the app and turn it back on some hours later, the green color is always too weak, it only start to show up when the brightness is over 60% as if it was on 1% brightness, if I set it to a lower brightness, it doesn’t show any light at all.

But the weirdest thing is that when I turn off the lamp by using the light switch and then turn it back on again, it always gets back to normal.

I want to know if this is some kind of bug (if so, is there any solution) or if my device is broken.
