Power BI Desktop Version: 2.85.681.0 64-bit (September 2020)
We can see a new feature about Total labels for stacked visuals.
When I tried to change format, I found a typo on formatting pane.
We can't understand ‘총 레이블’.
That should be ‘합계 레이블’.
And we are already using ‘합계’ as Total at table visual.
Thank you for your feedback. I will make a test on this and report internally if this issue can be considered as a bug.
