Bug: Locations not showing in the Year View

As observed by several forum members, occasionally the locations will not be showing in the Year View of the library.

There seems to be a limit of seven countries. If there are more countries or locations outside countries (oceans, bays), the list of countries will be omitted and it is impossible to get a map.

As a work-around, I have hidden photos in the moments, that would cause to have more countries in the particular year - areal photos taken out of the window on long distance flights for example. Or photos taken while sailing - all photos with a location showing as somewhere on the water, e.g. "North Atlantic Ocean". Hidden photos will only be hidden from the library views Moments, Years, Collections, but show in the albums. This way I can reduce the number of countries in the Years and still see the photos in the albums. Before I hide the photos, I add a keyword "Hide Temporarily", so I can quickly find the photos hidden for this reason.

The draw-back is, that hiding a photo will also hide its location. The location lookup is blocked for hidden photos.
