Because of the complexity of LED bulb electronics compared to old incandescent lights, dimming an LED bulb sometimes causes flickering in the bulb especially at low brightness.
The LED lights connected to the dimmer should add up to more than the dimmer's minimum load requirement expressed in Watts. If you have fewer bulbs than this minimum, consider installing a Bypass Module per dimmer switch. This will help against the bulbs flashing at startup or not turning off completely.
In some cases where the Bypass does not work, it has been found that the Inline Filter is the better solution.surge
