Steps to reproduce:
1. Open the Admin UI in your browser
2. Maybe reload the page (forcing full reload to prevent caching)
Sometimes, the Admin UI Counters on the Events page don't work.
The counters should work correctly
Workaround (if any):
Reload page until it works
The problem is the result of incorrect component initialization: The statsService is configured asynchronously which causes it to be used before it has been initialised.
