Cannot retrieve null values from a Task Report using Query Process Analytics

Hi All,

I am trying to query using Query Process Analytics to a task report containing all active task for a given process context.

And I am applying a query filter to fetch any null values from the report ( basically if a column field "c10" is null or not). 

Considering c10 data is coming from a PV variable , if i try to filter using a non - blank data it is working. But while checking for null values , it does not retrieve the actual null values output.

So if anyone could help me on this issue would be great.
