I'll try to describe the problem: when I assign a position in Map Panel with the second left icon (apply the target marker coordinates to all selected files), the content of metadata "Location" panel disappears (City, Location, State/Province, Country and ISO Country). Obviously I lose the content of this fields.
Thanks!
It seems like someone else recently reported this too, you might search the messages to see if you can find that thread.
