Photos location description is wrong - leaves out state. Will not hold an edit.

The metadata doesn't have a location name-- it has latitude and longitude coordinates. The name of the place located at those coordinates comes from a database that Apple keeps which is accessed through the internet by the Photos app. It sometimes has wrong names.

Where is your Photos Library located? Is it on an external drive? One of the only things weird about keeping a Photos Library on an external drive is that locations lookups seem to be inconsistent. I haven't checked this in a while, though.

In any case, try making a new Library on your internal drive and copying some of your Lexington pictures to that new Library--see if you get the same name.

Here's something else to try, if you like:

Get the free ExifTool Reader app, free from the App Store. Then export a Lexington picture to a Finder location, and examine the Exif metadata with the app. I did this with a picture just now, and it shows the coordinates of the location as

37 deg 25' 0.84" N, 122 deg 12' 15.40" W

Well, darn, that's not readable for Photos or Maps. So I changed "deg" to "°" (that's option-shift-8) to get this

37° 25' 0.84" N, 122° 12' 15.40" W

and I copied that into the Maps app--and I got the right place,

The Stanford Linear Accelerator Center. Try it Lexington and see what you get…

How are other people going to see it? The map is correct, right?

All you can do is send feedback to Apple:

I can't argue with that! The GPS coordinates remain correct, so there's no worry about actual effects to the pictures. They're OK-- it's just what you see that's strange.

Are you using Sequoia? I just created a Library on an external drive in Tahoe 26.2, and the location lookup seems to work with the few pictures I tried. It might have been fixed…

I actually saw what you did on Sequoia. (I am not upgrading to Tahoe until I finish getting some DV tapes into the computer.) So if Richard says it is fixed in Tahoe, you have hope.
