Photos not Importing Metadata

I have been using Photos since it replaced iPhoto.

When I edit my photos in Photoshop, I add a "Document Title" and other info to each image, which ends up in the images MetaData.

I create an album in Photos, then drag the folder of images from the finder into that album to import the images.

In the past when I imported these images, when I looked at the albums contents, the images would show the "document title" under each image.

But recently, this no longer happens.

Now after I import the photos, the album shows the Filename under the images.

I thought I forgot to add the metadata in photoshop, but when I reopen the images, the data is there.

Why is it no longer displaying the data properly after import?
