Context: 
When adding incompatible filters(e.g. running and completed filters), we display a warning message that there are no data because the filters are incompatible. However, after we added the multi definition, it is now possible to add contradicting filters and still have result back. For example, when applying running instances filter on one definition and completed instances filter on another. 

Hint:
This should be discussed with design to figure out a reasonable solution.
