GE Enbrighten light switch flips between two brightness settings on command

I am using Node Red to slowly turn up a light bulb to wake me up. The flow will periodically issue light.turn_on with brightness_pct to the Home Assistant API. Mostly it works correctly, and the light slowly gets brighter. However, in a few cases, it will go dimmer, then brighter when the light.turn_on command is issued. I debugged Node Red and confirmed that the flow was NOT sending these commands. I tailed OZQ_Log.txt and I noticed the following (it is trying to set the brightness_pct to 81):

Have you experienced similar behavior with your z-wave light switch?

I also noticed that when I tried to turn_off the light with the Home Assistant UI, the light turned off, turned back on, and then turned off again. This doesn’t always happen, but I noticed it after I finished trying to debug the node red flow.
