Running digikam 6.1.0 on Manjaro Linux Gnome Edition.

When I select an image -> Item -> Edit Geolocation, it shows the image at the proper location on the map.

When I select the image in the new window, Reverse Geocoding -> Apply reverse geocoding, under the Places tag, it shows all tags correctly in green color. Under the Places tag, there is already placeholder tags in red color.

However, when I close the geotagging window and go back to the album view, none of the tags under Places are marked!

What is happening here? How do I set it right?
