In the Grid view, Lightroom displays alerts
in image cells when the photos in your catalog have been changed
by another application. For example, if a photo has a one star rating
in Lightroom, and the photo has been updated to a two star rating
in another application, you need to decide which rating to respect.
Both cannot co-exist together. Lightroom lets you resolve conflicting
photo metadata by either overwriting its data in the catalog with
metadata from the photo or its sidecar XMP file, or overwriting
the metadata in the photo file or sidecar XMP file with its stored
data in the catalog.
In the Grid view, double-click the alert icon
in a cell.
In the Confirm dialog box, click one of the following:
Import Settings From
Disk
Imports the metadata from the photo or its sidecar XMP
file, which overwrites the photo’s data in the catalog.
Overwrite Settings
Exports metadata from the catalog to the photo file and
overwrites the data in the photo or its sidecar XMP file.
Do Nothing
Takes no action. If you select this option, be sure that
the photo’s metadata in the catalog doesn’t conflict with data in
the photo or its sidecar XMP file.
