I did not know that KD lists that driver, it is the RGBW driver formerly sold by intl-outdoor, Mtn still has some for sale. This KD driver is that same driver or an exact clone, including the same rather basic firmware. Your driver is skipping modes, the question is if the mode skipping is random, which could be a loose contact, or if the behaviour exactly repeatable, in which case being in certain modes by itself triggers changing to the next mode.
Btw, a while ago I had a closer look at this driver here: djozz driver hack #2. (was: Colour driver build, based on D882 sot89 transistor?)
