Pie Chart with SUM and GROUP BY not displaying properly

infotech table contains metrics about company platform usage
platform column is Mac, Linux, or Windows
users column is the number of users on that platform

SELECT
  platform,
  SUM(users) AS total
FROM infotech
GROUP BY platform

Expectation is pie slices for each platform, but a filled circle incorrectly displaying sum of all users is shown.

Other charts display the platform groups properly.

Can anyone explain why the pie chart slices are not being shown?
