I import photos into lightroom on a daily basis. All was sorking fine on Saturday. On sunday, I started to import some images, but the import page had lost it's renaming function. I've been using Lightroom 4, and just bought Photoshop Lightroom 6. did not fix the problem. I usually change from the camera format filename (IMGNNNN.jpg) to my own format, CAD000 tet string plus a sequencing number, currently at about 5200. How do I get the renaming page back?
