I came across a small issue with the geolocation plugin : I created a field with a street_address ID, which doesn't get auto populated after I've entered an address in the address field while all others (locality, postal_code, lat, lng) do.
To make the address field auto completed, please set its ID starts with address, like address_one. The plugin checks for address prefix. For details, please see the docs.
Update: Sorry, I misunderstood your question.
Regarding the problem, I think the street_address is not available from the response for your entered address. It's rarely used and not always available.
I had the same issue and can confirm street_address does not autopopulate as expected using the instructions in the documentation.
I ended up creating two fields and naming them street_number and route, and that works to populate the "street_address" for me, although through two fields instead of one.
