If Photos are apparently missing from an album, check the filter

Photos 4.0 on Mojave has a great new feature, the filters to exclude photos fron the view. (How to use the Filters in Photos 4.0) These filter settings will be saved for each album independently, when you switch to a different album, and the next time you open the album the photos will still be filtered. So, if you are seeing less photos in an album than the number of photos in the album, shown in the Info, check the filter "Showing" in the upper right corner of the browser. You may have forgotten to clear the filter, before you closed the album.

The "Showing" filter in the upper right corner of the viewer lets you specify criteria to select a subset of the photos, matching the criteria. Click the "Showing (only)" in the upper right corner to see the filter rules, that are currently checked.

For example:

Here the "Showing" filter has been set to show only the favorite videos.
