After duplicate images were imported from card to hard drive (despite having checked box "Do not import suspected duplicates"), I purposely deleted the folder and re-imported all the images for that date to avoid having to manually delete duplicates. The new specific date sub-folder (05-24-17) was inadvertently imported to 2016 folder, but I wanted it in 2017 folder. When I tried moving it to 2017 folder, it would not move. Anyone know how to resolve this?
You can move the folder using your operating system with Lightroom closed. Then open the Lightroom library where the folder will be shown as missing. Right-click on it and choose the option to find missing folder. Then you will be able to get things synchronized.
