Super chart live with device selector bug

If I use the super chart with multiple devices with device selector and I put the time of the chart into “Live”, when I switch the different devices, the different data are merged in the same chart.
Example:
I have device 1 with value 10, device 2 with value 5 and device 3 with value 15. I put the chart into “live” mode and switch between devices 1,2,3. After switching devices I have in the chart all the three values 10, 5 and 15.

Thanks for reporting. We will check it.
