Apple Photos in Peakto: "No images to show"

Apple Photos in Peakto: "No images to show"

Hello, 
I just started using Peakto.  I attached an Aperture library, of moderate size, it appeared to work well.  I also attached 2 Apple Photos libraries, one with 381 photos, this one worked equally well.  The other one, which has 7330 images or so, does not display any of them, although it went through the lengthy analysis process, showing the correct number of items that were analysed.  I can see the structure of the library but when I click on the top level of the hierarchy, which should show all its contents, I get "No images to show" and that there are no versions.  Am I doing something wrong?
