Previews Missing

[asislen]

I just imported 153 images into LR CC2015.5. Everything seemed to be normal. I then ran Helicon Focus on 5 images and created a DNG. When I returned to LR, the only image showing in the grid view was the 1 DNG created by Helicon Focus. In the left panel of the Library module, in the day's folder, it now shows only 1 image in the folder - the Helicon Focus DNG. If I synchronize the folder, it comes up with no files missing (I have Don't Import Dupes checked). When I use MAC finder, all the files are in the folder. Why aren't my images showing in the Library module??? Any ideas?!
Thanks, Alan

Do you have stacking turns on? Is the DNG cataloged in the same folder as the other 153 images? Is your Grid view showing the special collection called "Previous Import" or are you viewing the grid of a folder selected in the Folder panel?

Cletus, thanks. Problem solved! I inadvertently copy the images to my backup drive instead of the master image drive. Dragged them over and all is well!
