Yeelight RGBW Light Strip Level Control Broken on 2.2.8.152

Has anyone else noticed that their Yeelight bulbs have not been able to control level since the 2.2.8.152, or maybe even earlier, update? On, off, color temp, hue, and saturation all work fine, but anytime the level attempts to change, it fails and throws this error. Am I alone in this or is this a known bug?
