Hello, it looks like you have two devices in your datasource. One of them has the needed telemetry, and other one doesn't. Could you check your alias, please? Also, you could use the ${entityName} pattern in data keys labels to define if the duplicated names in the legend refer to one device.

Hello,

you are absolutely correct - the entity alias corresponds to 2 devices. My problem was resolved when I corrected the alias used. And this is not a bug, ofcourse.

Thank you for your help!
