Problem browsing photo library album

I am trying to import photos from photo library from an album I’ve created, but when I browse in fotomagico I don’t see all the photos in the album, only some of them, why?

I have the same problem after updating mojave. I can not browse all of my photos. Hoop that somebody out there could help us PRONTO. Since I’m trying to make a slideshow for my newborn grand doughter.
