Are the photos synced from the Iphone to Mac Photos, exported from Mac Photos, then imported into LR? If so, you're tripping over a longstanding bug in Mac Photos.
Mac Photos version 5 and later doesn't obey the industry standard for representing GPS coordinates in XMP files:

There are two workarounds:
1. Use the Exiftool utility to correct the .xmp files:

2. Uncheck the Photos option Export IPTC as XMP, which won't be helpful if you've added GPS coordinates to the photos in the Photos app.
