When we are trying to edit any static group then in the filter criteria the default value is seen as NULL. The old criteria on which the group was created is not seen.
Release : 20.3
Component : Operator Console
This is working as expected. While creating the static groups, the device selection can happen with different filter criteria. For example, create the group with name contains 'windows', add device to the group, clear the filter, apply another criteria and add devices again. In summary, the devices can be added multiple times with different criteria, unlike the dynamic group.
