I installed the PD- version dimmers all of the house, Feb 2020. Upto now they worked great. Now I've had 2 lights where the dimmer and light will and should be off but the light comes on to about 3% and then goes out. This cycle repeats over and over again. The only way to shut the light off so it doesn't happen is to pull the tab on the bottom of the dimmer out. Any help or reason this is starting to happen on all my lights?
