Donut Chart Units Bug

So I attached a few images to display the problem but essentially, you cannot use a computed column to display the units in the donut chart. The first picture I physically typed in the units I wanted and they are displayed fine. But when I switch it to being a computed column, it disappears from the chart. I even made a computed column that was just one letter and it still would not display, so I do not think it is too many characters or something like that.

I can reproduce this. Please make a video and submit it to the support team.
