nb-card-header doesn't render in initial load

**I'm submitting a bug report**

### Issue description

**Current behavior:**
When I login and redirect to the authenticated part of my application. I can't see `nb-card-header` until I refresh the page. The `nb-card-header` component can be seen in inspect even if it is not rendered.

**Before refresh (initial load)**

**After refresh**

This is happening when a user signs in and redirected to the dashboard. In dashboard I have multiple pages like this and none of them render `nb-card-header`. When I navigate site through dashboard with `router`, it doesn't render aswell but if I reload one of the pages or navigate by changing url it starts to render.

I can see `nb-card-header` component in the inspect even if it is not rendered.


**Expected behavior:**
It should render initially like other components.
