Pictures not showing up in folder

In LR CC pictures are not showing up in folders. The folder is there in the library and the proper folder in Explorer is indicated. The folder in Explorer is there as are the pictures. Imported pictures since this problem occured import properly with no problems. Colections are not effected.

Some may balk at this, for that one folder, right click on it, click on Synchronize. You may loose any edits hiwever.

No, do not use Synchronize Folder. That probably won't help, because the problem is that Lightroom knows that there are two images in this folder, but shows none. Is this the only folder that shows this behavior, or do (some) other folders show it too? The link above is more likely what happened here.

Your photos may be imported into a different folder (accidentally). Click on "All Photographs" and search for the desired folders by file name.

No, that is not the problem. Look at the screenshot. Lightroom shows in the folder panel that the folder contains two images, and yet in the main view it says there are no images in the folder. That is the corruption problem discussed in the link.
