When I click a thumbnail image in Lightroom CC it sometimes displays a totally different image. This is clearly a bug and needs to be fixed. Some of my 60000 photos may be named the same but I thought Lightroom would rename them when they are imported. Very frustrated I am having this issue
That does sound frustrating. Could you please go to Help menu > System Info and give us the first few lines of that dialog so we can see exactly what you're using. And is this happening on all of your devices or just one?
