Dutch postalcode in Mapbox Geocoding API - mapbox

Question

update it was a bug and they fixed it!
Dutch postalcodes contains 4 digits and 2 letters.
When entering 4 digits, it finds the global postalcode location, but when you add 2 letters (which corresponds to a street) the response doenst return the right location.
For example: 1012 returns a general postalcode location in Amsterdam. But when you enter 1012 AW it returns totally different results (different cities even). But it should return a specific location within the 1012 postalcode area.

The postal code that comes back don't have the two letter digits. How to get Mapbox to add the two letters?
