Blue 2-1 Issue with Zigbee Light Group

I’m having an issue with one of my Blue 2-1 switches that is bound (in Z2M0 to a zigbee group of 6 lights. Every time I go to dim them (up or down) by holding the up or down paddle the lights start to dim. However, the moment I release the paddle at my desired dim level, the lights all return to the original brightness before I started to dim them. This ONLY happens on the fir dimming attempt. If I repeated the same process again the lights will dim up or down and stay at that level when I release the paddle.

Has anyone seen this behavior before or have any tips for how to resolve it. It’s driving my wife (and consequently, me) crazy.
