Geocode Dataflow API job results are inaccurate

Question

I am trying to batch geocode using the REST API (to automate data uploads), but the response is extremely inaccurate. I think I have followed all the steps here:
https://learn.microsoft.com/en-us/bingmaps/spatial-data-services/geocode-dataflow-api/create-a-geocode-job-and-upload-data
And I'm using the correct Geocode Dataflow Data Schema (Version 2.0), using the exact parameters required for good results.

I have also tried one address using a REST Services URL
https://dev.virtualearth.net/REST/v1/Locations?countryRegion=US&adminDistrict=California&locality=Fontana&postalCode=92335&addressLine=15463%20Valley%20Blvd%2C%20Fontana%2C%20CA%2092335&userLocation=29.424349,-98.491142&maxResults=1&key={BingMapsKey}
and it works perfectly.

Here is an example of a geocode request:
