Hello,
I cannot deploy AVC configuration template on specific routers. PI version 3.6, update 3.
Having same problem on Cisco 4331:

NBAR VERSION:
Name: Advanced Protocol Pack
Version: 43.0
Publisher: Cisco Systems Inc.
NBAR Engine Version: 37
When I try to deploy from configuration from Network Devices->Device->Configuration->AVC->Enable App Visibility, then empty CLI preview appears:

If I click deploy then Undefined window appears.:
