Yeelight color bulb always on

Having problem with one of my color bulb, it stays on even with switch is off. I can control it using yeelight app, but can’t control it with my Alexa app. Can’t reset it as it can’t be switch on/off by manual switch.

It’s ok now, I just uninstall & reinstalled yeelight skill from my Amazon Alexa app. Working perfectly as before.
