Hello everyone. I have an issue displaying historical data in a 'Powertag' table. My variables are being historized 'On Change'.

When I display two data points separately (each in its own table), it works fine.

However, when I display both data points in a single table, it doesn't work correctly... it shows the same value twice, as seen in the attached image. I would appreciate any help. Thank you
