This is a major design flaw in LR's Map module that users have complained about for years. When the LR Map module adds suggested locations based on GPS coordinates, they appear in grey font (Mac) or italic font (Windows). Such "uncommitted" locations don't get saved to the photo's metadata. However, they will appear in the metadata of exported pics (provided you selected the correct export options). If you try to edit an uncommitted field, LR will clear all the other fields! You need to "commit" the fields first by clicking on the label (Sublocation, City, State, Country) of each field in each photo. Once a field has been committed, it will appear in normal font and will be saved to the photo's metadata. Embarrassingly clunky.
- Use the Geocoding Support plugin to add the location information (reverse geo-encoding). That plugin also provides commands for adding GPS coordinates from tracklogs. Many people find it superior to the Map module.
- Use the free Commit Locations command in the Any Tag plugin to commit all the location fields in a batch of photos.
Please add your vote and opinion to this feature request in the official Adobe feedback forum: Lightroom: improve control over reverse-geocoded Location metadata | Photoshop Family Customer Community. That will make it (a little) more likely Adobe might fix the problem before the next ice age.
hope they will add to lightroom cc 6 , at least the possibility to "commit" all the photos with 1 click
i will try the plugins
