LR don't show pictures in grid view and number in subfolders when opening

I've got a problem when I open my LR catalogue. I can't see the photo and number in the individual folders as I usually do

As shown in the attached image, there are 68692 images in the catalog, in subfolders the number of photos is not displayed, and as can be seen in the image on the far right, it is only in the bottom folder in the hierarchy that the number of photos and preview are displayed.

Until this problem arose, I have always been shown all photos when I open LR as well as shown the number of photos, and a preview in the individual subfolders all the way down through the hierarchy.

I have two other catalogs that give the same problem. I have tried opening LR from a backup file with the same result?

I have also created a new catalog, as a test, with the same result.

Sincerely
