Yeelight Ceiling Light 1ms off problems

After updating to firmware 2.0.2_0056 on May 9th, the main lamp is Sunset, Candle Ficker, and the atmosphere lamp is Sunset, Barthday Party, Dating Night, Romance, Candle Flicker. This is an impossible state. Factory reset has been performed more than 10 times with switch button 10 on/off, but to no avail, and to change Wi-Fi, but to no avail. I would like to know if this is a product issue or a firmware issue first. If it is a firmware issue, please downgrade or correct the error and update individually.
