working in LR cc and windows 10
recently when I work with plugins (silver efex, perfectly clear.....) or open a LR image in photoshop and save the images, I can see in the filmstrip that there's an extra image in the stack. I know how the stack works but I cannot unfold the stack and open the image. When I close LR and restart the program these images suddenly are available.
I have two catalogs : one is working well and the other gives the problem as described.
any idea what causes the trouble ?
Very likely there is a filter that doesn't match the hidden image. To troubleshoot, make sure the menu command Library > Enable Filters is unchecked (and yes, there is a keyboard shortcut). When it is unchecked, can you now expand and collapse the stack and see all the photos in it?
If that doesn't help, please post a full-resolution screenshot of the entire LR window. That will usually give clues as to what's going on.
