Similar to others I am having issues with flickering on the HS220 dimmer switch. I've run through the troubleshooting on the other threads but I am still having the same issues.

The switch is on the same circuit as two other HS220 which is flickering at the same frequency and timing as the other two.

The flickering isn't consistent, it happens for a little bit then stops and starts again.

These are the bulbs I am using:

Is it possible one of the bulbs that was sent to me is non-dimmable which is causing all three switches to flicker?
