One Flickering LED Bulb On Switch with 4 Bulbs

I have a swiych with 4 overhead recessed lights on it. I recently replaced the switch with a ZOOZ Z-wave dimmer switch. It worked great. Nor problems except I had mismatched LED bulbs so they didn’t dim evenly. I replaced them all with new EVEREADY Led Flood Light Bulbs, BR30, 65 Watts Equivalent (10W Led Bulb), 850 Lumen, 2700K Soft White Color, Dimmable, E26 Base Flood Lights for Recessed Cans, Energy Star and UL Certified.

They look great and dim very well with the new switch. BUT one of the bulbs was flickering every 30 seconds to a minute, randomly when at full brightness. It was only one of them so I replaced it with another of the exact same model. It’s doing the same thing, which leads me to believe it’s related to that particular socket. Interestingly, I did not have a problem with the old LED bulbs. I’m not sure how to troubleshoot this.
