Attached you can see a strange and weird stuff is happening to me.
This is a KPI, where i can put the actual month time average duration. If i set the Measure and format from the menu to "Duration" no matter if i use time(avg(CodiDataCalcDiffHoraInici)) or time(avg(CodiDataCalcDiffHoraInici),'hh:mm') i get the correct result: -01:21
Then i want to put it on the subtitle to show actual and previous month value. Like " Actual Time: -01:21 Previous Time: 02:03 "
But the problem is that when i put the expression on the Appearance menu
It shows 22:38 not -01:21 like the expresion set on the Measure menu.
I'm trying to search about the expresion "duration" time format or something like that but no luck by now.
