Wrong images are displayed in the Pins collection.
The Blue Pin collection contains 1 image, but this one has a red pin.
For the Red Pin collection, the number of images displayed is 6, but there are 74 images in the file window.
What is the problem?
All metadata has been written back.
Pins are not metadata.
And a file can have a red, green and blue pin, at the same time.
The file in your image has a red and a blue pin, and will show in both the red pin and the blue pin collection.
