Addresses not found in Geocode

We use Geocode to look up addresses for our routes that vans need to take to transport people.

For instance, we were able to find the addresses: Kleine Erven 2, Rosmalen,NB,Nederland, Kleine Erven 4, Rosmalen,NB,Nederland etc. However, eventhough the addresses are visible in the map-view we can’t find Kleine Erven 1, Rosmalen,NB,Nederland, Kleine Erven 3, Rosmalen,NB,Nederland, etc.

Any idea what could be the case of this and how we could fix this?
