Moes Zigbee LED Downlights Misbehaving

Good morning All. I have added my first 2 (Moes) Zigbee downlights to HA and they are not controlling correctly. When I switch them off in HA, they dim down but stay on. One of the devices changed from the colour I had it set as to a dim red when I switched it off. I am using the Sonoff Zigbee 3.0 USB dongle and Zigbee Home Assistant.

As I am still only just getting to grips with HA, any assistance would be greatly appreciated

Many thanks, Peter
