   ### Steps to reproduce
   
   1. I have a dimension have 'NULL'. What I mean is not all row have value.
   2. Use this dimension as Group By.
   3. Query.
   
   ### More
   I add a Filters into this form. The Filters is same dimension is 'event_name', relation is '!=', **but the value I don't input anything.**
   
   Then, I can see the expected results.
   
   And this is similar issue.
