LZW36 Light intermittently not turning off

I have two of the LZW36 Fan/Dimmer combos. Initially when I put them in I had that nasty disconnect problem but upgraded both to firmware 1.36 and they have been completely fine ever since. Now about a year later one of the two is intermittently not turning the light off (probably not the fan either but have not had the situation happen to confirm while the fan is running). Does not matter if I use the button or the hubitat its associated with to turn it off. I have also not made any changes to anything switch, hubitat, or otherwise in months.

Anyone have any suggestions on what I might do to fix this? I did reboot it using the breaker and the problem didn’t go away.
