Nothing returned when running SQL query in SQL tool for a single column DISTINCT or GROUP BY?

Since I'm just starting to use this aspect of IRIS I can't tell if this is a bug or some kind of nuance.  If I run a single column query like this, I get results:

However if I try to retrieve using a DISTINCT or GROUP BY, I get no results:

And again except with a GROUP BY, with no results:

If I add in some other columns I still get no results HOWEVER, if I add in a date column, I now get results:


What am I missing here?  Is this by design and if so, what governs whether a return set is returned or not?  I did purge my query cache in case something was happening there but it did not fix this.
