I have a folder named Nicaragua 2012. I also have a collection named Nica for Web in which I put those photos I want on my web site. Finally, I have created a smart collection that shows me Nicaragua photos that are not already on the web site. It is defined with 2 criteria:
Is in folder "Nicaragua 2012"
and
Is not in collection "Nica for Web"
This worked fine in LR4. Now this smart collection is picking up not only all the photos it is supposed to, but also all the photos from a folder named "Christmas 2012."
This is truly bizarre, any ideas?
