Total card concatenates values instead of adding them up for calculating the total for stacked columns

Hi, in one of my Lookerstudio dashboards, I have a stacked bar chart with three calculated fields as metrics. I have the total card enabled for the chart. The total card shows the correct value for each metric, but not for the total value of the three. Instead of adding up each metric, it shows a value that is a concatenation of the three values. This weird total value then is handled as a number with thousand separators. Can you please look into this bug?

Yikes.

I wonder if Looker Studio is viewing those values as strings instead of numbers? And trying to “add” them together by concatenation instead of addition.

Can you double check the data type of the calculated fields for me and make sure that they are numbers?

Hi Sam, this might have been just a temp glitch as it started calculating the totals correctly 7-10 days ago.
