Hi everyone,
Please do NOT delete the data from your locations, this isn't really a matter of what data is in which fields, but rather how we're displaying it.
We've released a change to show an icon (looks like a location pin) and clickable / hoverable box for the address details. I hope that addresses the obvious confusion I caused by putting a hover over something that doesn't look like you can interact with it.
It may help to explain what initiated these changes to begin with. Previously, if Google returned city / county / state (region) / country data (as mapped from the fields locality / administrative_area_level_1 / administrative_area_level_2 / country) we would leave the "place name" blank (unless it got data from Google's "establishment" field). This was a problem for some users because certain locations like "Caribbean" seemed to geolocate but when you saved them, the address data was blank. We fixed that in two ways, first the Google field "colloquial_area" now also maps to Place Name, and second if Google returns no data from establishment or colloquial_area then we're now populating the Place Name field with Google's "formatted_address" field (which is what you see when you select the auto-complete row). This also fixes problems where the user might specify a location like "Taj Majal" and it would seem to geolocate perfectly, but after you save the data you get the structured fields (Agra, Uttar Pradesh, India) but the words Taj Majal are lost. I have the same issue with my birth location, Wright-Patterson Air Force Base in Ohio.
We could simply display it all in the profile, but often Google's formatted address is the same information as the structure fields, for example if we strung them all together you get locations like "Pike County, OH, USA, Pike County, Ohio, United States". If they were all wholly duplicate we wouldn't take the formatted address into the place name field, however refer back to the Taj Majal problem.
Thanks for you patience and once you've had a chance to see the new clickable location pin, let me know your thoughts.
