Deeply nested feature module routing

Question

I have a feature module called Overview in which I lazy-load another feature module called TravelDetails which also contains some routing.

The bad thing: the routes of TravelDetails are not appended as child routes to the lazy-loaded route path, but instead it seems like it is layered with the Overview routes somehow.

TravelDetails routes:

Overview routes:

So, whenever the TravelDetails module is already laoded and I go to .../overview, which is the parent path that activates the Overview module, the TravelDetails path is activated and the TravelDetailsComponent gets loaded.
