Metadata info below Folder

I noticed tonight that the Metadata button to view all the metadata (located below Folder in the info panel) doesn’t appear for all of my photos - it only seems to appear for certain photos that were recently imported from Google Photos - is there a reason for this? I don’t remember it being unavailable for certain (most) photos before.

Just answered my own question - it seems to show up when I download the original to my computer. Is there not a way for it to appear if the original exists elsewhere?
