Not a bug Alerts showing up

[somosung]

Affected version

2.0

Why is that, when i am logged in, the number from Alerts only appear when i refresh page? Here at xenforo theme.
This keeps happening to me. I leave page, and after coming back, there is no alert, but when i change page, a number appear

That is the designed behaviour - they are not push alerts.
