Upgraded from Lightroom 5.4 where I had no issues. With Lightroom 6.1.1, import photos from camera card to new folder under date order on laptop and apply lightroom edits. Close Lightroom. The next time I open lightroom the new folder is not displayed and I have to synchronise the parent folder to re-import the photos with associated edits into the Lightroom Catalog. Subsequent closing and opening Lightroom includes the folders as expected. While the work around resolves the issue, it is annoying.
What is your operating system?
What folder is your LR catalog in?
Operating System: Windows 7 Pro 64-bit Service Pack 1
Folder for LR catalog:
> SSD divided into 2 partitions (C: for operating system 165GB with 50GB free, G: for data 50GB with 15GB free). The photos are imported into G: under folder 2015. I do Lightroom adjustments on files in this location and them move via the Lightroom interface to the 500GB Hard drive.
> 500GB Hard Drive (D:): Lightroom Catalog is located on this drive under parent directory Lightroom>General.
