Steps to Reproduce
Ensure that List v3 is enabled on the incident table.
Navigate to incident_list.do.
Add the following condition: [Created] [is less than] [3 Hours before] [Activity Due].
Run the query.
Change the "is less than" to "is greater than".
Run the query
Note that no condition is added to the query
Instead of changing the operator from "is less than" to "is greater than", remove the old condition and create a new one with the desired operator.
