geocoder is geocoding from a field it is not requested to geocode from

Problem/Motivation

On my custom facility entity, I have a geofield field_location and an address field field_address. field_location geocodes from field_address and field_address reverse geocodes from field_location. But I also have a plain text field field_name which I want to use as a pure label, and if I have that filled in then field_location geocodes from it, then field_address reverse geocodes from field_location, and the content I actually entered into one or both of those fields is lost.

Steps to reproduce

Set up as above. I used ECK.

Proposed resolution

Stop it from doing that :)
