Thanks but I don't see the problem.
The folder named 19980101-Francis has 55 images in it. If you click on that folder do you see 55 images in the Grid view?
The next folder down, ### Cort's Wedding has at least one subfolder, which is denoted by the solid grey color triangle, and has 139 images in either the top level folder or in the subfolder/subfolders under that top level folder. If you click the solid grey color triangle how many subfolders does it contain and what number of images are in each subfolder?
If you click on one of them or the top level folder are all the images displayed.
You do have multiple folders that only contain 1, 2, 3, 4, 5, 6 images in them. If one of those is selected then the only images in the grid view area will only be those 1, 2, 3, or 4 images that are in that specific folder.
In one of your other screen shots you show part of the folders section and the Grid view section and in the grid view there are 2 images of Go Carts. You have a folder named Kart Racing that only has 2 images in it. As far I can tell LR is displaying all the images that are in that folder.
Select one of the other folders that has multiple images in it, like one of the top folder that I mentioned above, and post another screen shot of the FULL LR window and make sure the folder you have selected in the Folders area is displayed, IE Highlighted.
But to be honest I don't see the problem you are talking about.
As far as I can tell LR is displaying all the images that are in the folder you have selected.
