Edits not synced fully from iCloud to Mac
I have recently set up iCloud for photos. I have edited a number of photos on my iPhone, such as added filters, cropped, etc. The sync of photos, albums etc seem to work great when I open Photos on Mac OS (El Capitan), and I can SEE that the photos are edited, but when I click "Edit" in Photos, none of the changes can be see there. It's as if the editing options are untouched.
For example, I added the filter Fade to a photo on iPhone. When I open the photo in Photos on Mac OS, I can see that the filter has been applied, but when I click "Edit" and select Filters, it says "None", while on the iPhone it says "Fade".
Nothing is spinning or syncing so the download seems to be complete.
Why can't I see the editing options?
MacBook Pro with Retina display, OS X El Capitan (10.11.6)
