This just started happening when switching from the library to develop module: I select a photo to develop in the library module, and when I switch to the develop module, it's not the photo I've chosen. It appears as though the first photo in the library is the one that's seen in the develop module. Please help, because this means I need to arrow through hundreds of photos in each library to get to the one I want to develop. Thank you!
Are you updated? Not sure if is exactly your issue, but similar enough to check. Here: Lightroom: No Image displays in Develop Module after Deletion of Other Images | Photoshop Family Customer Community
"Adobe released Lightroom 6.9/CC2015.9 today. This issue should be corrected in this release. Please give it a try and let us know if you see any further issues."
Thank you! I updated Lightroom and it worked! I appreciate your help.
