In a scrum board, we can click the 3 dots button on a sprint to see total estimate of its issues.
How do we turn this on for Backlog? I know for sure that this can be done, because I have somehow enabled it on a test project, but when setting up our actual project, I can't seem to find it.
As you can see in the screenshots, the option button is visible on TPS Board's backlog, but not on PE board's backlog.
