Acknowledge option in context menu on Problems page

Steps to reproduce:

1. Go to Monitoring -> Problems
2. Click on an unresolved problem cell
3. Check popup menu

Result:
Acknowledge option
Expected:
As I know, the acknowledge option in the context menu should only be on these pages:
Monitoring → Dashboard (Trigger overview widget)
Monitoring → Overview → Trigger overview
Monitoring → Screens → (Trigger overview element)
