Departures sometime show too few departures

Original issue

Describe the bug
I expect to use the Nearby-tab to find the next departures that are relevant for me, so I know when I have to leave from home to be able to catch the next bus.

In some situations, the app only shows one departure that is relevant for me, and that departure leaves at the bus stop before I manage to get there.

To Reproduce
Steps to reproduce the behavior:

1. Go to Nearby-tab
2. Search for "Waldemar Aunes veg 10C"
3. Look for departure: "3 Lohove via sentrum"

Expected behavior
II expect to see at least one departure that is relevant for me, that i realistically can manage to get on.
