Run with no feature that has an entry in the Spatial Index table (Range).
A run that has no feature should not have a range.
A problem existed in the code in V4.0.x that could lead to this condition. The problem was fixed in 4.1.x, so this problem should only show up on V4.0 migrated models.
The run has an invalid range, so operations based on ranges could be affected (for example, queries or fitting windows).
What You Should Do
The problem will be fixed as soon the run is recomputed.
