Could be a bug. I saw a similar issue on floorplan with custom icons. That was solved recently. You could test it in a beta environment if the issue still is available.
Be aware latest beta has no OpenZwave integration.

Thanks for explaining, testing and offering a solution. I still use ozw so won’t go to beta just yet. Probably in a few weeks I will try a new domoticz install with MQTT. Hope that will resolve some Zigbee issues too.
