I have an indicator widget configured to calculate the total length of pipe cleaned today.

I also have a reference set to show the total length of pipe cleaned yesterday.

What I want to see is something like this:

except for the time frame "today" compared to "yesterday."
However, yesterday being Sunday, no pipes were cleaned. My widget is displaying my 'No Data' text but I know that pipes were cleaned today. If I change the statistic to count, the widget does what it is supposed to which is show me today's results compared to yesterday's.
Has anyone else experienced this issue?
