## Cause

The rule does not exist in any policy package. However, it is used in one of the policy layers or in a shared layer.

## Solution

1. Connect to SmartConsole.  

2. Open 'Manage Layers' (***Menu \> Manage Layers*** ).  

3. Uncheck ***'Show only shared layers'*** .
4. Search for the relevant layer and fix the problematic rule.   
   **Note:** If the policy package was deleted and the layer is not in use, you can remove it.
