How to edit a filter
Edits can always be made to filters. Any filter edits you make affect every rule that filter is bound to.
To edit a filter:
1. Starting in the dashboard, click Rules.
The rules and filters designer appears, where rules and filters can be created and edited.
2. Ensure the Filters tab is selected.
3. Select a filter from the list.
The filter opens and is ready to edit.
4. Make your changes.
5. Click Save.
 
You successfully edited a filter. If the filter is bound to a rule that is connected in the active layout, your filter edits take effect immediately.
